Properties for calling an AWS service's API action from your state machine across regions.

Example

declare const myBucket: s3.Bucket;
const getObject = new tasks.CallAwsServiceCrossRegion(this, 'GetObject', {
  region: 'ap-northeast-1',
  service: 's3',
  action: 'getObject',
  parameters: {
    Bucket: myBucket.bucketName,
    Key: sfn.JsonPath.stringAt('$.key')
  },
  iamResources: [myBucket.arnForObjects('*')],
});

---

action

Type: string

The API action to call.

Use camelCase.

---

iamResources

Type: string[]

The resources for the IAM statement that will be added to the Lambda function role's policy to allow the state machine to make the API call.

---

region

Type: string

The AWS region to call this AWS API for. Example

'us-east-1'

---

service

Type: string

The AWS service to call in AWS SDK for JavaScript v3 format.

See also: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/ Example

's3'

---

additionalIamStatements?

Type: PolicyStatement[] (optional, default: no additional statements are added)

Additional IAM statements that will be added to the state machine role's policy.

Use in the case where the call requires more than a single statement to be executed, e.g. rekognition:detectLabels requires also S3 permissions to read the object on which it must act.

---

assign?

Type: { [string]: any } (optional, default: Not assign variables)

Workflow variables to store in this step.

Using workflow variables, you can store data in a step and retrieve that data in future steps.

See also: https://docs.aws.amazon.com/ja_jp/step-functions/latest/dg/workflow-variables.html

---

comment?

Type: string (optional, default: No comment)

A comment describing this state.

---

credentials?

Type: Credentials (optional, default: None (Task is executed using the State Machine's execution role))

Credentials for an IAM Role that the State Machine assumes for executing the task.

This enables cross-account resource invocations.

See also: https://docs.aws.amazon.com/step-functions/latest/dg/concepts-access-cross-acct-resources.html

---

endpoint?

Type: string (optional, default: Do not override API endpoint.)

The AWS API endpoint.

---

heartbeat?⚠️

⚠️ Deprecated: use heartbeatTimeout

Type: Duration (optional, default: None)

Timeout for the heartbeat.

---

heartbeatTimeout?

Type: Timeout (optional, default: None)

Timeout for the heartbeat.

[disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface

---

iamAction?

Type: string (optional, default: service:action)

The action for the IAM statement that will be added to the Lambda function role's policy to allow the state machine to make the API call.

By default the action for this IAM statement will be service:action.

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.

---

inputPath?

Type: string (optional, default: $)

JSONPath expression to select part of the state to be the input to this state.

May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}.

---

integrationPattern?

Type: IntegrationPattern (optional, default: IntegrationPattern.REQUEST_RESPONSE for most tasks. IntegrationPattern.RUN_JOB for the following exceptions: BatchSubmitJob, EmrAddStep, EmrCreateCluster, EmrTerminationCluster, and EmrContainersStartJobRun.)

AWS Step Functions integrates with services directly in the Amazon States Language.

You can control these AWS services using service integration patterns.

Depending on the AWS Service, the Service Integration Pattern availability will vary.

See also: https://docs.aws.amazon.com/step-functions/latest/dg/connect-supported-services.html

---

outputPath?

Type: string (optional, default: $)

JSONPath expression to select part of the state to be the output to this state.

May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}.

---

outputs?

Type: any (optional, default: $states.result or $states.errorOutput)

Used to specify and transform output from the state.

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.

See also: https://docs.aws.amazon.com/step-functions/latest/dg/concepts-input-output-filtering.html

---

parameters?

Type: { [string]: any } (optional, default: no parameters)

Parameters for the API action call in AWS SDK for JavaScript v3 format.

---

queryLanguage?

Type: QueryLanguage (optional, default: JSONPath)

The name of the query language used by the state.

If the state does not contain a queryLanguage field, then it will use the query language specified in the top-level queryLanguage field.

---

resultPath?

Type: string (optional, default: $)

JSONPath expression to indicate where to inject the state's output.

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

---

resultSelector?

Type: { [string]: any } (optional, default: None)

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.

See also: https://docs.aws.amazon.com/step-functions/latest/dg/input-output-inputpath-params.html#input-output-resultselector

---

retryOnServiceExceptions?

Type: boolean (optional, default: true)

Whether to retry on the backend Lambda service exceptions.

This handles Lambda.ServiceException, Lambda.AWSLambdaException, Lambda.SdkClientException, and Lambda.ClientExecutionTimeoutException with an interval of 2 seconds, a back-off rate of 2 and 6 maximum attempts.

---

stateName?

Type: string (optional, default: The construct ID will be used as state name)

Optional name for this state.

---

taskTimeout?

Type: Timeout (optional, default: None)

Timeout for the task.

[disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface

---

timeout?⚠️

⚠️ Deprecated: use taskTimeout

Type: Duration (optional, default: None)

Timeout for the task.
