I'm currently working on an ASP.Net MVC 4 application that uses PayPal to process credit card transactions. I've gotten most of everything setup with the PayPal RESTFul API and for some reason PayPal's latest version of their SDK just doesn't want to work (through NUGET) so I decided to make the api calls myself using ASP.Net's latest and greatest HttpClient() (like it this way better anyways)

What I need to do is the following (copied from PayPal's documentation)

 curl -v https://api.sandbox.paypal.com/v1/payments/payment \
 -H "Content-Type:application/json" \
 -H "Authorization:Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG" \
 -d   '{
        "intent": "sale",
        "rest_of_the_data": "I didn't include it here"
      }'

What I'm stuck on right now is the third parameter -H "Authorization:Bearer EEwJ6tF9x5WCIZDYzyZGaz6Khbw7raYRIBV_WxVvgmsG" \ here is what I have that doesn't work:

using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(                                    System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1} {2}", "Authorization", accessToken.token_type, accessToken.access_token))));
    var response = client.PostAsync<Payment>(endPoint + "/v1/payments/payment", payment, new JsonMediaTypeFormatter());
    if (response.Result.IsSuccessStatusCode)
       {
          var responseContent = response.Result.Content;
          var responseString = responseContent.ReadAsAsync<Payment>().Result;
       }
}

With the above code I'm getting the following response:

Result = {StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Date: Thu, 13 Jun 2013 07:06:50 GMT
  Server: Apache-Coyote/1.1
  Content-Length: 0
  Content-Type: application/json
}}

Now I'm sure I am passing the right credentials but I believe that its not correctly formatted according to the -H "Authorization:Bearer... I believe that I should not be using client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(... but I can't seem to find a replacement to make this work. What should I be using?

Any help in this regard would be greatly appreciated.

It appears you are incorrectly setting the header value. Try the following to see if it works:

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(accessToken.access_token));

Thanks for the help but I got the same error, I double checked all the access_Token and it's right but I'm getting the same status code 401 unauthorized –  hjavaher Jun 13 '13 at 8:37
    
ok, also have you checked if after the token conversion the value is the same as the one you used in curl example you gave. –  Kiran Challa Jun 13 '13 at 8:40
    
No I haven't, the example that I provided above was given by PayPal. the access token is only good for 8 hours. What I'm thinking is that the your solution translates into curl .... -u [access token] instead of curl... -H [authorization....] based on my use of it for getting the access token –  hjavaher Jun 13 '13 at 8:52
