CallAwsServiceProps Struct
Properties for calling an AWS service's API action from your state machine.
Example
declare const myBucket: s3.Bucket;
const getObject = new tasks.CallAwsService(this, 'GetObject', {
service: 's3',
action: 'getObject',
parameters: {
Bucket: myBucket.bucketName,
Key: sfn.JsonPath.stringAt('$.key')
},
iamResources: [myBucket.arnForObjects('*')],
});
Properties
Use camelCase.

Use in the case where the IAM action name does not match with the API service/action name, e.g. s3:ListBuckets requires s3:ListAllMyBuckets.

Depending on the AWS Service, the Service Integration Pattern availability will vary.
default
Default: IntegrationPattern.REQUEST_RESPONSE for most tasks. IntegrationPattern.RUN_JOB for the following exceptions: BatchSubmitJob, EmrAddStep, EmrCreateCluster, EmrTerminationCluster, and EmrContainersStartJobRun.
May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}.

When specified, the value overrides the state output default. The output field accepts any JSON value (object, array, string, number, boolean, null). Any string value, including those inside objects or arrays, will be evaluated as JSONata if surrounded by {% %} characters. Output also accepts a JSONata expression directly.
Default: $states.result or $states.errorOutput

May also be the special value JsonPath.DISCARD, which will cause the state's input to become its output.
