Asynchronous processes are exposed as Jobs. A job can be created automatically by the system or by a request made by the user.
When a request is made to the API which results in a job being created the HTTP response code will be 201 Accepted and the body of the response contains the ID of the created job.
In some situations the Job may not be immediately available from the JobStatusHandler so any attempt to retrieve it should allow the request to be retried.
