How do I return a different HTTP status code than the basic ones? (i.e 202 instead of 200)
You are able to gain more control over the HTTP headers (such as status codes) through the ServerServiceCall. Utilizing that mechanism you can use the invokeWithHeaders method, which responds with ResponseHeader in addition to the Response itself. You can then use this control of the ResponseHeader to set the HTTP status as is best suited for your needs.
