SqsSendMessage

A StepFunctions Task to send messages to SQS queue.

Import

import { SqsSendMessage } from 'aws-cdk-lib/aws-stepfunctions-tasks';

Or use the module namespace:

import * as stepfunctions_tasks from 'aws-cdk-lib/aws-stepfunctions-tasks';
// stepfunctions_tasks.SqsSendMessage

Properties

Configuration passed to the constructor as SqsSendMessageProps.

messageBodyRequired

TaskInput

The text message to send to the queue.

queueRequired

IQueue

The SQS queue that messages will be sent to.

Default: $

resultSelectorOptionalinherited from TaskStateBaseProps

The JSON that will replace the state's raw result and become the effective result before ResultPath is applied. You can use ResultSelector to create a payload with values that are static or selected from the state's raw result.

Default: - None
