Question

I’m trying to connect to a API (In this case freeagent) to grab some data. I’ve used Googles OAuth Playground to generate me a token.

var req = (HttpWebRequest)WebRequest.Create("https://api.freeagent.com/v2/recurring_invoices");

req.Headers["Authorization"] = "Bearer " + Convert.ToBase64String(Encoding.ASCII.GetBytes(_accessToken));

req.ContentType = "application/xml";
req.Accept = "application/xml";
req.Method = "GET";

// and get the response
var resp = req.GetResponse();
var streamIn = new StreamReader(resp.GetResponseStream());
returnData = streamIn.ReadToEnd();
streamIn.Close();

return resp;

Now I’m loosly trying to conver the following : https://dev.freeagent.com/docs/using_curl

I constantly get a Bad Request HTTP 400 – Anyone have any suggestions on what could be causing this problem?

The solution to this, is to pass the UserAgent as well.

Example…

req.UserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17";
