azure function using app services and with access to Microsoft Dynamic 365 CRM online

Question

I have an Azure function that is working. However, I am trying to also use the azure function to do authentication to get access to Microsoft Dynamic CRM.

When trying to get my token is when my problem occurs.

I hope someone can help me get this working.

TraceWriter log)
        {
            log.Info("C# HTTP trigger function processed a request.");

            // parse query parameter
           string name = req.GetQueryNameValuePairs()
               .FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
               .Value;


            string organizationUrl = "https://xxxxxx.crm.dynamics.com";
            string api = "https://xxxxxx.crm.dynamics.com/api/data/v9.1";

            AuthenticationParameters ap = AuthenticationParameters.CreateFromUrlAsync(
                new Uri(api)).Result;

            var clientId = "833ab393-56ef-6ed6-10e7-89accb8fea8b";
            var secertKey = ".N:?.h6NfT3FVCNcfdvzfbZzPZguq6t3";

            var creds = new ClientCredential(clientId, secertKey);
            log.Info("client:" + clientId);

            AuthenticationContext authContext = new AuthenticationContext(ap.Authority);
            var token = authContext.AcquireTokenAsync(ap.Resource, creds).Result.AccessToken;

            log.Info("Token : " + token);

            Uri serviceUrl = new Uri(organizationUrl + @"/xrmservices/2011/organization.svc/web?SdkClientVersion=v9.1");

            using (var sdkService = new OrganizationWebProxyClient(serviceUrl, false))
            {
                sdkService.HeaderToken = token;

                var _orgService = (IOrganizationService)sdkService != null ? (IOrganizationService)sdkService : null;
                log.Info("Get Org Service");
            }

            return name == null
                ? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
                : req.CreateResponse(HttpStatusCode.OK, "Hello " + name);
        }
   }

}
