Question

I tried all the way, but getting error

When I test the api using postman and passing the param in Body as raw data {"reference":{"Id":"User","documentId":"56e0"}} [NOTE: NOT in x-www-form-urlencoded or form-data]. It works and getting response with data.

You can see that the postman screenshot shows the request is text/json, not text/plain. — Avi
@Avi Thanks, But I am setting the content type [theRequest setValue:mACCEPTVALUE forHTTPHeaderField:mCONTENTTYPELABEL]; where mACCEPTValUE is text/json — Praveen-K
So your question is really how to get AF to send your request as text/json, because the error you posted clearly shows that it isn't. — Avi
@Avi Yes Avi. I am passing parameter {"reference":{"sheetId":"User","documentId":"56e02ac1f045d90f508b45fb"}} as raw data — Praveen-K
I see where it's going wrong. It's not the request that's wrong, it's the response. You are expecting a JSON response, but you're getting a 400 response which includes text explaining the error. If you decode the returned data, you get HTTP 400 Missing parameter: 'reference'. — Avi

if you are using AFNetworking, try accepting content types explicitly

let serviceManager = AFHTTPSessionManager()
serviceManager.responseSerializer.acceptableContentTypes = NSSet(objects: "text/plain", "text/html", "application/json", "audio/wav", "application/octet-stream", "text/javascript") as? Set

This worked for me
