  Authentication error returned from express checkout using permissions

  Feb 15, 2013 08:53 PM|LINK

  I have been banging my head against a wall for the last couple of days trying to get express checkout working in a simple asp.net mvc application with permissions. In every iteration I receive some type of unauthorized message. I believe that the token is being generated correctly I can't seem to find how to get the sand box to accept the generated header. Can someone please point me in the right direction? I am using a service reference for the soap api. Below is the action calling the setexpresscheckout method. I have removed username, password and url strings for the post.

  public ActionResult BuySomething()
  {
      String accessToken = Session["access_token"].ToString();
      String tokenSecret = Session["token_secret"].ToString();
      String normalizedUrl = String.Empty;
      String normalizedRequestParameters = String.Empty;
      String oauthTimeStamp = String.Empty;
      Hashtable queryParams = null;
  
      String url = "https://www.sandbox.paypal.com/webscr?cmd=_express-checkout&token=";
  
      Hashtable map = OauthSignature.getAuthHeader(username, password, accessToken, tokenSecret,
                                          OauthSignature.HTTPMethod.POST,
                                          expressCheckoutEndpoint, queryParams);
  
      CustomSecurityHeaderType header = new CustomSecurityHeaderType();
  
      SetExpressCheckoutReq req = new SetExpressCheckoutReq()
      {
          SetExpressCheckoutRequest = new SetExpressCheckoutRequestType()
          {
              Version = "98.0",
                      
              SetExpressCheckoutRequestDetails = new SetExpressCheckoutRequestDetailsType()
              {
                  OrderDescription = "Test",
                  OrderTotal = new BasicAmountType()
                  {
                      Value = "10.00",
                      currencyID = CurrencyCodeType.USD
                  },
                  CancelURL = ConfigurationManager.AppSettings["PaypalExpressCancel"],
                  ReturnURL = ConfigurationManager.AppSettings["PaypalExpressSuccess"]
              }
          }
      };
  
      PayPalAPIAAInterfaceClient client = new PayPalAPIAAInterfaceClient();
      client.Endpoint.Address = new EndpointAddress(expressCheckoutEndpoint);
  
      using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
      {
          HttpRequestMessageProperty httpRequestMessageProperty = new HttpRequestMessageProperty();
          httpRequestMessageProperty.Headers["X-PAYPAL-AUTHORIZATION"] = "token=" + accessToken +
                                                                      ",signature=" + map["Signature"].ToString() +
                                                                      ",timestamp=" + map["TimeStamp"].ToString();
  
          SetExpressCheckoutResponseType responseType = client.SetExpressCheckout(ref header, req);
  
          url += responseType.Token;
      }
  
      return Redirect(url);
  }
