A 400 response means that the HTTP server that the request went to has said that the request is invalid.

Why?

Who knows! Maybe the URL you sent in the request has malformed arguments (in the query string) or maybe it requires arguments that you didn't supply. Or maybe the problem is the other headers.

Or maybe it just doesn't like you.

I suggest that you compare the request you are sending with either the web site's API documentation or a request sent by a (real) browser. And if that fails, ask the folks who look after the web server you are sending the requests to.
