Restsharp returns 403 while Postman returns 200

Question

This is the (modified) snippet that Postman gives for successful call to my page.

var client = new RestClient("http://sub.example.com/wp-json/wp/v2/users/me");
var request = new RestRequest(Method.GET);
request.AddHeader("authorization", "Basic anVyYTp3MmZacmo2eGtBOHJsRWrt");
IRestResponse response = client.Execute(request);

But when placed in my c# app it returns 403 forbidden, while Postman makes it and recieves 200. The same thing happens when I use httpclient in my app (403).

Answer 1

Use RestClient.Authenticator instead:

var client = new RestClient("http://sub.example.com/wp-json/wp/v2/users/me")
{ 
      Authenticator = new HttpBasicAuthenticator("User", "Pass")
};

var request = new RestRequest(Method.GET);
IRestResponse response = client.Execute(request);

Edit:

Since the issue (as mentioned in the comments) is the fact that RestSharp doesn't flow the authentication through redirects, I'd suggest going with a combination of HttpClient with a HttpClientHandler where you set the authentication to flow.
