User request completion callback

When submitting a request, an optional HTTP callback can be specified which will be invoked when the request completes or fails. The callback is an HTTP POST to the exact URL provided. Only one attempt is made to reach the URL provided. The contents of the HTTP request match the response from the Querying a request status and retrieving results above.

Headers

x-requestid: Contains the request_id received when the request was submitted
x-status: One of the following indicating the status of the request:

Status	Description
“Completed”	The request has finished processing and the user callback, if provided has been called.
“Failed”	An error occurred processing the request.

x-error: If the request failed, this would contain an error message.
x-userdata: This will contain the user data supplied with the original request.

Body

If the status is “Completed” the body of the request contains the results from the translation. If the status is “Failed” the body of the request contains the same error message provided in the x-error header.

Using meta controls

One or more meta control values are provided in the meta_controls query parameter. The control values are provided using the following structure:

{control}:{value},{control}:{value},etc.

E.g.
meta_controls=gender:female,genre:newswire

The meta_controls available for a model is provided in the meta_controls array of the model description returned by the Query available translation models method.
