          Here is an example of how to use this method::
  
              with open('my_manifest.zip') as manifest:
                  sub.upload({'organization_id': org.id}, manifest)
  
          :param synchronous: What should happen if the server returns an HTTP
              202 (accepted) status code? Wait for the task to complete if
              ``True``. Immediately return the server's response otherwise.
          :param kwargs: Arguments to pass to requests.
          :returns: The server's response, with all JSON decoded.
          :raises: ``requests.exceptions.HTTPError`` If the server responds with
              an HTTP 4XX or 5XX message.
