Optimized integrations for Step Functions

The following topics include the supported APIs, parameters, and request/response syntax in the Amazon States Language for coordinating other AWS services. The topics also provide example code. You can call Optimized integrations services directly from the Amazon States Language in the Resource field of a Task state.

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.

• Optimized integrations pattern support is different for each integration.

• Express Workflows do not support Run a Job (.sync) or Wait for Callback (.waitForTaskToken).

• For more information, see Standard vs. Express Workflows.
