If it's a file and you are trying to upload a particular media type, the header 'Content-Type': 'application/x-www-form-urlencoded' does not seem right to me. Have a look at the appropriate media type here:

http://www.iana.org/assignments/media-types/media-types.xhtml

Also, you serialize data to JSON, if your data is binary you will need to change that to a byte array.

You might find some useful info here:

Also you set a token both in your URL and your header, I'd recommend to set it in the header only.
