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.

#outputs ⇒ Object? (readonly)

Note:

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).
