For more information, see the Amazon States Language Specification and Statelint, a tool that validates Amazon States Language code. Within a state machine, there can be only one state that's designated as the start state, designated by the value of the StartAt field in the top-level structure. This state is the one that is executed first when the execution starts. The state machine definition is an object, where the format of the object matches the format of your AWS SAM template file, for example, JSON or YAML. State machine definitions adhere to the Amazon States Language. For an example of an inline state machine definition, see Examples.
