Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon EventBridge helps you to respond to state changes in your AWS resources. When your resources change state, they automatically send events into an event stream. You can create rules that match selected events in the stream and route them to targets to take action. You can also use rules to take action on a predetermined schedule. For example, you can configure rules to:

  • Automatically invoke an AWS Lambda function to update DNS entries when an event notifies you that Amazon EC2 instance enters the running state

  • Direct specific API records from AWS CloudTrail to an Amazon Kinesis data stream for detailed analysis of potential security or availability risks

  • Periodically invoke a built-in target to create a snapshot of an Amazon EBS volume

For more information about the features of Amazon EventBridge, see the Amazon EventBridge User Guide.

Sending a Request Using CloudWatchEvents

var cloudwatchevents = new AWS.CloudWatchEvents();
cloudwatchevents.listRuleNamesByTarget(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the CloudWatchEvents object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var cloudwatchevents = new AWS.CloudWatchEvents({apiVersion: '2015-10-07'});

You can also set the API version globally in AWS.config.apiVersions using the cloudwatchevents service identifier:

AWS.config.apiVersions = {
  cloudwatchevents: '2015-10-07',
  // other service API versions
};

var cloudwatchevents = new AWS.CloudWatchEvents();

Method Details

activateEventSource(params = {}, callback) ⇒ AWS.Request

Activates a partner event source that has been deactivated. Once activated, your matching event bus will start receiving events from the event source.

Note: This operation is performed by AWS customers, not by SaaS partners.

Service Reference:

Examples:

Calling the activateEventSource operation

var params = {
  Name: 'STRING_VALUE' /* required */
};
cloudwatchevents.activateEventSource(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • Name — (String)

      The name of the partner event source to activate.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createEventBus(params = {}, callback) ⇒ AWS.Request

Creates a new event bus within your account. This can be a custom event bus which you can use to receive events from your own custom applications and services, or it can be a partner event bus which can be matched to a partner event source.

Note: This operation is used by AWS customers, not by SaaS partners.

Service Reference:

Examples:

Calling the createEventBus operation

var params = {
  Name: 'STRING_VALUE', /* required */
  EventSourceName: 'STRING_VALUE'
};
cloudwatchevents.createEventBus(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • Name — (String)

      The name of the new event bus.

      The names of custom event buses can't contain the / character. You can't use the name default for a custom event bus because this name is already used for your account's default event bus.

      If this is a partner event bus, the name must exactly match the name of the partner event source that this event bus is matched to. This name will include the / character.

    • EventSourceName — (String)

      If you're creating a partner event bus, this specifies the partner event source that the new event bus will be matched with.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • EventBusArn — (String)

        The ARN of the new event bus.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createPartnerEventSource(params = {}, callback) ⇒ AWS.Request

Called by an SaaS partner to create a partner event source.

Note: This operation is not used by AWS customers.

Each partner event source can be used by one AWS account to create a matching partner event bus in that AWS account. A SaaS partner must create one partner event source for each AWS account that wants to receive those event types.

A partner event source creates events based on resources in the SaaS partner's service or application.

An AWS account that creates a partner event bus that matches the partner event source can use that event bus to receive events from the partner, and then process them using AWS Events rules and targets.

Partner event source names follow this format:

aws.partner/partner_name/event_namespace/event_name

  • partner_name is determined during partner registration and identifies the partner to AWS customers.

  • For event_namespace, we recommend that partners use a string that identifies the AWS customer within the partner's system. This should not be the customer's AWS account ID.

  • event_name is determined by the partner, and should uniquely identify an event-generating resource within the partner system. This should help AWS customers decide whether to create an event bus to receive these events.

Service Reference:

Examples:

Calling the createPartnerEventSource operation

var params = {
  Account: 'STRING_VALUE', /* required */
  Name: 'STRING_VALUE' /* required */
};
cloudwatchevents.createPartnerEventSource(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • Name — (String)

      The name of the partner event source. This name must be unique and must be in the format partner_name/event_namespace/event_name . The AWS account that wants to use this partner event source must create a partner event bus with a name that matches the name of the partner event source.

    • Account — (String)

      The AWS account ID of the customer who is permitted to create a matching partner event bus for this partner event source.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

      • EventSourceArn — (String)

        The ARN of the partner event source.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

deactivateEventSource(params = {}, callback) ⇒ AWS.Request

deleteRule(params = {}, callback) ⇒ AWS.Request

Deletes the specified rule.

Before you can delete the rule, you must remove all targets, using RemoveTargets.

When you delete a rule, incoming events might continue to match to the deleted rule. Allow a short period of time for changes to take effect.

Managed rules are rules created and managed by another AWS service on your behalf. These rules are created by those other AWS services to support functionality in those services. You can delete these rules using the Force option, but you should do so only if you're sure that the other service isn't still using that rule.

Service Reference:

Examples:

Calling the deleteRule operation

var params = {
  Name: 'STRING_VALUE', /* required */
  EventBusName: 'STRING_VALUE',
  Force: true || false
};
cloudwatchevents.deleteRule(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})

          Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format.

        • InputPath — (String)

          The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath.

        • InputTransformer — (map)

          Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.

          • InputPathsMap — (map<String>)

            Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output to be sent to the target.

            InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.

            The keys can't start with "AWS".

          • InputTemplaterequired — (String)

            Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value>. The InputTemplate must be valid JSON.

            If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

            • The placeholder can't be used as an object key

            • Object values can't include quote marks

            The following example shows the syntax for using InputPathsMap and InputTemplate.

            "InputTransformer":

            {

            "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

            "InputTemplate": "<instance> is in state <status>"

            }

            To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:

            "InputTransformer":

            {

            "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

            "InputTemplate": "<instance> is in state \"<status>\""

            }

        • KinesisParameters — (map)

          The custom parameter that you can use to control the shard assignment when the target is a Kinesis data stream. If you don't include this parameter, the default is to use the eventId as the partition key.

          • PartitionKeyPathrequired — (String)

            The JSON path to be extracted from the event and used as the partition key. For more information, see Amazon Kinesis Streams Key Concepts in the Amazon Kinesis Streams Developer Guide.

        • RunCommandParameters — (map)

          Parameters used when you are using the rule to invoke Amazon EC2 Run Command.

          • RunCommandTargetsrequired — (Array<map>)

            Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.

            • Keyrequired — (String)

              Can be either tag: tag-key or InstanceIds.

            • Valuesrequired — (Array<String>)

              If Key is tag: tag-key, Values is a list of tag values. If Key is InstanceIds, Values is a list of Amazon EC2 instance IDs.

        • EcsParameters — (map)

          Contains the Amazon ECS task definition and task count to be used if the event target is an Amazon ECS task. For more information about Amazon ECS tasks, see Task Definitions in the Amazon EC2 Container Service Developer Guide.

          • TaskDefinitionArnrequired — (String)

            The ARN of the task definition to use if the event target is an Amazon ECS task.

          • TaskCount — (Integer)

            The number of tasks to create based on TaskDefinition. The default is 1.

          • LaunchType — (String)

            Specifies the launch type on which your task is running. The launch type that you specify here must match one of the launch type (compatibilities) of the target task. The FARGATE value is supported only in the Regions where AWS Fargate with Amazon ECS is supported. For more information, see AWS Fargate on Amazon ECS in the Amazon Elastic Container Service Developer Guide.

            • "EC2"
            • "FARGATE"
          • NetworkConfiguration — (map)

            Use this structure if the ECS task uses the awsvpc network mode. This structure specifies the VPC subnets and security groups associated with the task and whether a public IP address is to be used. This structure is required if LaunchType is FARGATE because the awsvpc mode is required for Fargate tasks.

            If you specify NetworkConfiguration when the target ECS task doesn't use the awsvpc network mode, the task fails.

            • awsvpcConfiguration — (map)

              Use this structure to specify the VPC subnets and security groups for the task and whether a public IP address is to be used. This structure is relevant only for ECS tasks that use the awsvpc network mode.

              • Subnetsrequired — (Array<String>)

                Specifies the subnets associated with the task. These subnets must all be in the same VPC. You can specify as many as 16 subnets.

              • SecurityGroups — (Array<String>)

                Specifies the security groups associated with the task. These security groups must all be in the same VPC. You can specify as many as five security groups. If you don't specify a security group, the default security group for the VPC is used.

              • AssignPublicIp — (String)

                Specifies whether the task's elastic network interface receives a public IP address. You can specify ENABLED only when LaunchType in EcsParameters is set to FARGATE.

                Possible values include:
                • "ENABLED"
                • "DISABLED"
          • PlatformVersion — (String)

            Specifies the platform version for the task. Specify only the numeric portion of the platform version, such as 1.1.0.

            This structure is used only if LaunchType is FARGATE. For more information about valid platform versions, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

          • Group — (String)

            Specifies an ECS task group for the task. The maximum length is 255 characters.

        • BatchParameters — (map)

          If the event target is an AWS Batch job, this contains the job definition, job name, and other parameters. For more information, see Jobs in the AWS Batch User Guide.

          • JobDefinitionrequired — (String)

            The ARN or name of the job definition to use if the event target is an AWS Batch job. This job definition must already exist.

          • JobNamerequired — (String)

            The name to use for this execution of the job, if the target is an AWS Batch job.

          • ArrayProperties — (map)

            The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.

            • Size — (Integer)

              The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.

          • RetryStrategy — (map)

            The retry strategy to use for failed jobs if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1–10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.

            • Attempts — (Integer)

              The number of times to attempt to retry, if the job fails. Valid values are 1–10.

        • SqsParameters — (map)

putPermission(params = {}, callback) ⇒ AWS.Request

Running PutPermission permits the specified AWS account or AWS organization to put events to the specified event bus. Rules in your account are triggered by these events arriving to an event bus in your account.

For another account to send events to your account, that external account must have a rule with your account's event bus as a target.

To enable multiple AWS accounts to put events to an event bus, run PutPermission once for each of these accounts. Or, if all the accounts are members of the same AWS organization, you can run PutPermission once specifying Principal as "*" and specifying the AWS organization ID in Condition, to grant permissions to all accounts in that organization.

If you grant permissions using an organization, then accounts in that organization must specify a RoleArn with proper permissions when they use PutTarget to add your account's event bus as a target. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide.

The permission policy on an event bus can't exceed 10 KB in size.

Service Reference:

Examples:

Calling the putPermission operation

var params = {
  Action: 'STRING_VALUE', /* required */
  Principal: 'STRING_VALUE', /* required */
  StatementId: 'STRING_VALUE', /* required */
  Condition: {
    Key: 'STRING_VALUE', /* required */
    Type: 'STRING_VALUE', /* required */
    Value: 'STRING_VALUE' /* required */
  },
  EventBusName: 'STRING_VALUE'
};
cloudwatchevents.putPermission(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • EventBusName — (String)

      The event bus associated with the rule. If you omit this, the default event bus is used.

    • Action — (String)

      The action that you're enabling the other account to perform. Currently, this must be events:PutEvents.

    • Principal — (String)

      The 12-digit AWS account ID that you are permitting to put events to your default event bus. Specify "" to permit any account to put events to your default event bus.

      If you specify "" without specifying Condition, avoid creating rules that might match undesirable events. To create more secure rules, make sure that the event pattern for each rule contains an account field with a specific account ID to receive events from. Rules with an account field don't match any events sent from other accounts.

    • StatementId — (String)

      An identifier string for the external account that you're granting permissions to. If you later want to revoke the permission for this external account, specify this StatementId when you run RemovePermission.

    • Condition — (map)

      This parameter enables you to limit the permission to accounts that fulfill a certain condition, such as being a member of a certain AWS organization. For more information about AWS Organizations, see What Is AWS Organizations? in the AWS Organizations User Guide.

      If you specify Condition with an AWS organization ID and specify "*" as the value for Principal, you grant permission to all the accounts in the named organization.

      The Condition is a JSON string that must contain Type, Key, and Value fields.

      • Typerequired — (String)

        The type of condition. Currently, the only supported value is StringEquals.

      • Keyrequired — (String)

        The key for the condition. Currently, the only supported key is aws:PrincipalOrgID.

      • Valuerequired — (String)

        The value for the key. Currently, this must be the ID of the organization.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

putRule(params = {}, callback) ⇒ AWS.Request

Creates or updates the specified rule. Rules are enabled by default or based on value of the state. You can disable a rule using DisableRule.

A single rule watches for events from a single event bus. Events generated by AWS services go to your account's default event bus. Events generated by SaaS partner services or applications go to the matching partner event bus. If you have custom applications or services, you can specify whether their events go to your default event bus or a custom event bus that you have created. For more information, see CreateEventBus.

If you're updating an existing rule, the rule is replaced with what you specify in this PutRule command. If you omit arguments in PutRule, the old values for those arguments aren't kept. Instead, they're replaced with null values.

When you create or update a rule, incoming events might not immediately start matching to new or updated rules. Allow a short period of time for changes to take effect.

A rule must contain at least an EventPattern or ScheduleExpression. Rules with EventPatterns are triggered when a matching event is observed. Rules with ScheduleExpressions self-trigger based on the given schedule. A rule can have both an EventPattern and a ScheduleExpression, in which case the rule triggers on matching events as well as on a schedule.

When you initially create a rule, you can optionally assign one or more tags to the rule. Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only rules with certain tag values. To use the PutRule operation and assign tags, you must have both the events:PutRule and events:TagResource permissions.

If you are updating an existing rule, any tags you specify in the PutRule operation are ignored. To update the tags of an existing rule, use TagResource and UntagResource.

Most services in AWS treat : or / as the same character in Amazon Resource Names (ARNs). However, EventBridge uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event that you want to match.

In EventBridge, you could create rules that lead to infinite loops, where a rule is fired repeatedly. For example, a rule might detect that ACLs have changed on an S3 bucket, and trigger software to change them to the desired state. If you don't write the rule carefully, the subsequent change to the ACLs fires the rule again, creating an infinite loop.

To prevent this, write the rules so that the triggered actions don't refire the same rule. For example, your rule could fire only if ACLs are found to be in a bad state, instead of after any change.

An infinite loop can quickly cause higher than expected charges. We recommend that you use budgeting, which alerts you when charges exceed your specified limit. For more information, see Managing Your Costs with Budgets.

        The value for the specified tag key.

    • EventBusName — (String)

      The event bus to associate with this rule. If you omit this, the default event bus is used.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • RuleArn — (String)

        The Amazon Resource Name (ARN) of the rule.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

putTargets(params = {}, callback) ⇒ AWS.Request

Adds the specified targets to the specified rule, or updates the targets if they're already associated with the rule.

Targets are the resources that are invoked when a rule is triggered.

You can configure the following as targets in EventBridge:

  • EC2 instances

  • SSM Run Command

  • SSM Automation

  • AWS Lambda functions

  • Data streams in Amazon Kinesis Data Streams

  • Data delivery streams in Amazon Kinesis Data Firehose

  • Amazon ECS tasks

  • AWS Step Functions state machines

  • AWS Batch jobs

  • AWS CodeBuild projects

  • Pipelines in AWS CodePipeline

  • Amazon Inspector assessment templates

  • Amazon SNS topics

  • Amazon SQS queues, including FIFO queues

  • The default event bus of another AWS account

Creating rules with built-in targets is supported only on the AWS Management Console. The built-in targets are EC2 CreateSnapshot API call, EC2 RebootInstances API call, EC2 StopInstances API call, and EC2 TerminateInstances API call.

For some target types, PutTargets provides target-specific parameters. If the target is a Kinesis data stream, you can optionally specify which shard the event goes to by using the KinesisParameters argument. To invoke a command on multiple EC2 instances with one rule, you can use the RunCommandParameters field.

To be able to make API calls against the resources that you own, Amazon EventBridge needs the appropriate permissions. For AWS Lambda and Amazon SNS resources, EventBridge relies on resource-based policies. For EC2 instances, Kinesis data streams, and AWS Step Functions state machines, EventBridge relies on IAM roles that you specify in the RoleARN argument in PutTargets. For more information, see Authentication and Access Control in the Amazon EventBridge User Guide.

If another AWS account is in the same Region and has granted you permission (using PutPermission), you can send events to that account. Set that account's event bus as a target of the rules in your account. To send the matched events to the other account, specify that account's event bus as the Arn value when you run PutTargets. If your account sends events to another account, your account is charged for each sent event. Each event sent to another account is charged as a custom event. The account receiving the event isn't charged. For more information, see Amazon EventBridge Pricing.

If you're setting an event bus in another account as the target and that account granted permission to your account through an organization instead of directly by the account ID, you must specify a RoleArn with proper permissions in the Target structure. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide.

For more information about enabling cross-account events, see PutPermission.

Input, InputPath, and InputTransformer are mutually exclusive and optional parameters of a target. When a rule is triggered due to a matched event:

  • If none of the following arguments are specified for a target, the entire event is passed to the target in JSON format (unless the target is Amazon EC2 Run Command or Amazon ECS task, in which case nothing from the event is passed to the target).

  • If Input is specified in the form of valid JSON, then the matched event is overridden with this constant.

  • If InputPath is specified in the form of JSONPath (for example, $.detail), only the part of the event specified in the path is passed to the target (for example, only the detail part of the event is passed).

  • If InputTransformer is specified, one or more specified JSONPaths are extracted from the event and used as values in a template that you specify as the input to the target.

When you specify InputPath or InputTransformer, you must use JSON dot notation, not bracket notation.

When you add targets to a rule and the associated rule triggers soon after, new or updated targets might not be immediately invoked. Allow a short period of time for changes to take effect.

This action can partially fail if too many requests are made at the same time. If that happens, FailedEntryCount is nonzero in the response, and each entry in FailedEntries provides the ID of the failed target and the error code.

});

Parameters:

  • params (Object) (defaults to: {})
    • Rule — (String)

      The name of the rule.

    • EventBusName — (String)

      The name of the event bus associated with the rule. If you omit this, the default event bus is used.

    • Targets — (Array<map>)

      The targets to update or add to the rule.

      • Idrequired — (String)

        The ID of the target.

      • Arnrequired — (String)

        The Amazon Resource Name (ARN) of the target.

      • RoleArn — (String)

        The Amazon Resource Name (ARN) of the IAM role to be used for this target when the rule is triggered. If one rule triggers multiple targets, you can use a different IAM role for each target.

      • Input — (String)

        Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format.

      • InputPath — (String)

        The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath.

      • InputTransformer — (map)

        Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.

        • InputPathsMap — (map<String>)

          Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output to be sent to the target.

          InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.

          The keys can't start with "AWS".

        • InputTemplaterequired — (String)

          Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value>. The InputTemplate must be valid JSON.

          If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

          • The placeholder can't be used as an object key

          • Object values can't include quote marks

          The following example shows the syntax for using InputPathsMap and InputTemplate.

          "InputTransformer":

          {

          "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

          "InputTemplate": "<instance> is in state <status>"

          }

          To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:

          "InputTransformer":

          {

          "InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

          "InputTemplate": "<instance> is in state \"<status>\""

          }

      • KinesisParameters — (map)

        The custom parameter that you can use to control the shard assignment when the target is a Kinesis data stream. If you don't include this parameter, the default is to use the eventId as the partition key.

        • PartitionKeyPathrequired — (String)

          The JSON path to be extracted from the event and used as the partition key. For more information, see Amazon Kinesis Streams Key Concepts in the Amazon Kinesis Streams Developer Guide.

      • RunCommandParameters — (map)

        Parameters used when you are using the rule to invoke Amazon EC2 Run Command.

        • RunCommandTargetsrequired — (Array<map>)

          Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.

          • Keyrequired — (String)

            Can be either tag: tag-key or InstanceIds.

          • Valuesrequired — (Array<String>)

            If Key is tag: tag-key, Values is a list of tag values. If Key is InstanceIds, Values is a list of Amazon EC2 instance IDs.

      • EcsParameters — (map)

        Contains the Amazon ECS task definition and task count to be used if the event target is an Amazon ECS task. For more information about Amazon ECS tasks, see Task Definitions in the Amazon EC2 Container Service Developer Guide.

          The ARN of the task definition to use if the event target is an Amazon ECS task.

        • TaskCount — (Integer)

          The number of tasks to create based on TaskDefinition. The default is 1.

        • LaunchType — (String)

          Specifies the launch type on which your task is running. The launch type that you specify here must match one of the launch type (compatibilities) of the target task. The FARGATE value is supported only in the Regions where AWS Fargate with Amazon ECS is supported. For more information, see AWS Fargate on Amazon ECS in the Amazon Elastic Container Service Developer Guide.

          Possible values include:
          • "EC2"
          • "FARGATE"
        • NetworkConfiguration — (map)

          Use this structure if the ECS task uses the awsvpc network mode. This structure specifies the VPC subnets and security groups associated with the task and whether a public IP address is to be used. This structure is required if LaunchType is FARGATE because the awsvpc mode is required for Fargate tasks.

          If you specify NetworkConfiguration when the target ECS task doesn't use the awsvpc network mode, the task fails.

          • awsvpcConfiguration — (map)

            Use this structure to specify the VPC subnets and security groups for the task and whether a public IP address is to be used. This structure is relevant only for ECS tasks that use the awsvpc network mode.

            • Subnetsrequired — (Array<String>)

              Specifies the subnets associated with the task. These subnets must all be in the same VPC. You can specify as many as 16 subnets.

            • SecurityGroups — (Array<String>)

              Specifies the security groups associated with the task. These security groups must all be in the same VPC. You can specify as many as five security groups. If you don't specify a security group, the default security group for the VPC is used.

            • AssignPublicIp — (String)

              Specifies whether the task's elastic network interface receives a public IP address. You can specify ENABLED only when LaunchType in EcsParameters is set to FARGATE.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
        • PlatformVersion — (String)

          Specifies the platform version for the task. Specify only the numeric portion of the platform version, such as 1.1.0.

          This structure is used only if LaunchType is FARGATE. For more information about valid platform versions, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

        • Group — (String)

          Specifies an ECS task group for the task. The maximum length is 255 characters.

      • BatchParameters — (map)

        If the event target is an AWS Batch job, this contains the job definition, job name, and other parameters. For more information, see Jobs in the AWS Batch User Guide.

        • JobDefinitionrequired — (String)

          The ARN or name of the job definition to use if the event target is an AWS Batch job. This job definition must already exist.

        • JobNamerequired — (String)

          The name to use for this execution of the job, if the target is an AWS Batch job.

        • ArrayProperties — (map)

          The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.

          • Size — (Integer)

            The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.

        • RetryStrategy — (map)

          The retry strategy to use for failed jobs if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1–10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.

          • Attempts — (Integer)

            The number of times to attempt to retry, if the job fails. Valid values are 1–10.

      • SqsParameters — (map)

        Contains the message group ID to use when the target is a FIFO queue.

        If you specify an SQS FIFO queue as a target, the queue must have content-based deduplication enabled.

        • MessageGroupId — (String)

          The FIFO message group ID to use as the target.

tagResource(params = {}, callback) ⇒ AWS.Request

Assigns one or more tags (key-value pairs) to the specified EventBridge resource. Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values. In EventBridge, rules can be tagged.

Tags don't have any semantic meaning to AWS and are interpreted strictly as strings of characters.

You can use the TagResource action with a rule that already has tags. If you specify a new tag key for the rule, this tag is appended to the list of tags associated with the rule. If you specify a tag key that is already associated with the rule, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a resource.

Service Reference:

Examples:

Calling the tagResource operation

var params = {
  ResourceARN: 'STRING_VALUE', /* required */
  Tags: [ /* required */
    {
      Key: 'STRING_VALUE', /* required */
      Value: 'STRING_VALUE' /* required */
    },
    /* more items */
  ]
};
cloudwatchevents.tagResource(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • ResourceARN — (String)

      The ARN of the rule that you're adding tags to.

    • Tags — (Array<map>)

      The list of key-value pairs to associate with the rule.

      • Keyrequired — (String)

        A string that you can use to assign a value. The combination of tag keys and values can help you organize and categorize your resources.

      • Valuerequired — (String)

        The value for the specified tag key.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

testEventPattern(params = {}, callback) ⇒ AWS.Request

Tests whether the specified event pattern matches the provided event.

Most services in AWS treat : or / as the same character in Amazon Resource Names (ARNs). However, EventBridge uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event that you want to match.

Service Reference:

Examples:

Calling the testEventPattern operation

var params = {
  Event: 'STRING_VALUE', /* required */
  EventPattern: 'STRING_VALUE' /* required */
};
cloudwatchevents.testEventPattern(params, function(err, data) {

      The event pattern. For more information, see Event Patterns in the Amazon EventBridge User Guide.

    • Event — (String)

      The event, in JSON format, to test against the event pattern.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.
