AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

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 Events:

Creating rules with built-in targets is supported only in the Amazon Web Services 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 Lambda and Amazon SNS resources, EventBridge relies on resource-based policies. For EC2 instances, Kinesis Data Streams, Step Functions state machines and API Gateway REST APIs, 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 Amazon Web Services 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 is not charged. For more information, see Amazon EventBridge Pricing.

Input, InputPath, and InputTransformer are not available with PutTarget if the target is an event bus of a different Amazon Web Services account.

If you are setting the event bus of another account as the target, and that account granted permission to your account through an organization instead of directly by the account ID, then you must specify a RoleArn with proper permissions in the Target structure. For more information, see Sending and Receiving Events Between Amazon Web Services 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:

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 non-zero in the response and each entry in FailedEntries provides the ID of the failed target and the error code.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginPutTargets and EndPutTargets.

Namespace: Amazon.CloudWatchEvents
Assembly: AWSSDK.CloudWatchEvents.dll
Version: 3.x.y.z

Syntax

C# 
public abstract Task<PutTargetsResponse> PutTargetsAsync(
         PutTargetsRequest request,
         CancellationToken cancellationToken
)

Parameters

request
Type: Amazon.CloudWatchEvents.Model.PutTargetsRequest

Container for the necessary parameters to execute the PutTargets service method.

cancellationToken
Type: System.Threading.CancellationToken

A cancellation token that can be used by other objects or threads to receive notice of cancellation.

Return Value


Type: Task<PutTargetsResponse>
The response from the PutTargets service method, as returned by CloudWatchEvents.

Exceptions

ExceptionCondition
ConcurrentModificationException There is concurrent modification on a rule, target, archive, or replay.
InternalException This exception occurs due to unexpected causes.
LimitExceededException The request failed because it attempted to create resource beyond the allowed service quota.
ManagedRuleException This rule was created by an Amazon Web Services service on behalf of your account. It is managed by that service. If you see this error in response to DeleteRule or RemoveTargets, you can use the Force parameter in those calls to delete the rule or remove targets from the rule. You cannot modify these managed rules by using DisableRule, EnableRule, PutTargets, PutRule, TagResource, or UntagResource.
ResourceNotFoundException An entity that you specified does not exist.
