The service automatically sets HTTP response codes. Both default response codes and reason phrase are shown and can be modified in Endpoint Configuration tab.

You can alternatively set your own - usually more granular - response status codes via CTL code anywhere in any of the job components via the setResponseStatus function.

Additional response headers can be set, or the default ones overridden, using setResponseHeader. It is possible to overwrite the value of the same header multiple times in the job as the final HTTP response (including headers) is transferred to the client only after all of job’s components have finished running.
