Workday Web Service Authentication with C#

I am looking to use Workday WebService v30.0

https://community.workday.com/sites/default/files/file-hosting/productionapi/Human_Resources/v30.0/Human_Resources.html

I am trying to replicate example https://community.workday.com/node/191970 and I keep getting "invalid username and password". I know that username and password is correct, because it works in SOAP UI.

Here is my code: 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;

using GetWorkerSample.HumanResources;

namespace GetWorkerSample
{
    class Program
    {
        static void Main(string[] args)
        {
            //Instantiate an instance of WCF generated proxy and set the Endpoint
            Human_ResourcesPortClient hr = new Human_ResourcesPortClient();
            hr.Endpoint.Address = new EndpointAddress(args[0]);


            //Configure Port
            hr.ClientCredentials.UserName.UserName = "user@tenant";
            hr.ClientCredentials.UserName.Password = "password";

            //Instantiate Header for the request
            //Confiure Header
            Workday_Common_HeaderType header = new Workday_Common_HeaderType();
            header.Include_Reference_Descriptors_In_Response = false;
            header.Include_Reference_Descriptors_In_ResponseSpecified = false;


            //Setting up filter to get data for 5 workers
            //Response Filter
            Response_FilterType responseFilter = new Response_FilterType();
            responseFilter.Count = 5;
            responseFilter.Page = 1;
            responseFilter.PageSpecified = true;
            responseFilter.CountSpecified = true;


            //Configure Criteria
            Worker_Request_CriteriaType requestCriteria = new Worker_Request_CriteriaType();
            requestCriteria.Exclude_Inactive_Workers = true;
            requestCriteria.Exclude_Inactive_WorkersSpecified = true;


            // Formating response to contain Personal information, Employment information and Compensation
            //Configure Response Group
            Worker_Response_GroupType responseGroup = new Worker_Response_GroupType();
            responseGroup.Include_Reference = true;
            responseGroup.Include_Personal_Information = true;
            responseGroup.Include_Compensation = true;
            responseGroup.Include_Employment_Information = true;
            responseGroup.Include_ReferenceSpecified = true;
            responseGroup.Include_Personal_InformationSpecified = true;
            responseGroup.Include_CompensationSpecified = true;
            responseGroup.Include_Employment_InformationSpecified = true;
            responseGroup.Include_Organizations = true;
            responseGroup.Include_OrganizationsSpecified = true;

            //updating preferences for the request
            //Configure Request
            Get_Workers_RequestType request = new Get_Workers_RequestType();
            request.Request_Criteria = requestCriteria;
            request.Response_Filter = responseFilter;
            request.Response_Group = responseGroup;
            request.version = "v30.0";

            //Invoke HR getworker api via Proxy
            try
            {
                var Testtworker = hr.Get_Workers(header, request).Response_Data;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

            Console.Read();

        }
    }
}

hr.Get_Workers failed with error:

Any ideas or pointers ? Thanks all.

Solution

  • I had to use CustomBinding with authenticationMode="UserNameOverTransport" and I no longer have authentication issues.

    (Posting this in case anyone encounters same issue with Workday API)
