Adds the specified targets to the specified rule, or updates the targets if they are already associated with the rule.
Targets are the resources that are invoked when a rule is triggered.
You can configure the following as targets for CloudWatch Events:
AWS Lambda functions
Streams in Amazon Kinesis Streams
Delivery streams in Amazon Kinesis Firehose
Amazon ECS tasks
AWS Step Functions state machines
AWS Batch jobs
Pipelines in Amazon Code Pipeline
Amazon Inspector assessment templates
Amazon SNS topics
Amazon SQS queues, including FIFO queues
The default event bus of another AWS account
Note that creating rules with built-in targets is supported only in the AWS Management Console.
For some target types,
PutTargets provides target-specific parameters.
If the target is an Amazon Kinesis 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
To be able to make API calls against the resources that you own, Amazon CloudWatch
Events needs the appropriate permissions. For AWS Lambda and Amazon SNS resources,
CloudWatch Events relies on resource-based policies. For EC2 instances, Amazon Kinesis
streams, and AWS Step Functions state machines, CloudWatch Events relies on IAM roles
that you specify in the
RoleARN argument in
For more information, see Authentication
and Access Control in the Amazon CloudWatch Events 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 by setting 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 when you
PutTargets. If your account sends events to another account, your
account is charged for each sent event. Each event sent to antoher account is charged
as a custom event. The account receiving the event is not charged. For more information
on pricing, see Amazon CloudWatch
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, then the entire event is passed to the target in JSON form (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,
then 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, then 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
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. Please 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
FailedEntryCount is non-zero in the response and each entry
FailedEntries provides the ID of the failed target and the error code.
For .NET Core and PCL this operation is only available in asynchronous form. Please refer to PutTargetsAsync.
