Optimized integrations for Step Functions
You can call Optimized integrations services directly from the Amazon States Language in the Resource field
of a Task state. The following topics include the supported APIs, parameters, request/response syntax in the Amazon States Language for coordinating other AWS services.
You can use three service integration patterns:
-
Request a Response (default) - wait for HTTP response, then go to the next state
-
Run a Job (.sync) - wait for the job to complete
-
Wait for Callback (.waitForTaskToken) - pause a workflow until a task token is returned
Standard Workflows and Express Workflows support the same integrations but not the same integration patterns.
Express Workflows support Request Response, but they do not support Run a Job (.sync) or Wait for Callback (.waitForTaskToken).
For more information, see Choosing workflow type in Step Functions.
