Create Work Item in Team Services Through API

Question

I'm trying to create a web app (hosted on Azure) for clients to be able to submit work items to our team services page. Basically a support ticket page so they don't have to call to explain their backlog all the time.

Below is the class and method i've made to create work items, following Microsoft's sample code, with some obvious changes for privacy reasons. This method is triggered by a button click, and so far I cannot get it to create any work items.

using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using Newtonsoft.Json;

 namespace customapp
 {
  public class CreateWorkItem
  {


    public void CreateWorkItemMethod()
    {

        string personalAccessToken = "xxxxxxxxx";
        string credentials = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "xxx", personalAccessToken)));

        Object[] patchDocument = new Object[1];

        patchDocument[0] = new { op = "add", path = "/fields/System.Title", value = "Test" };


        using (var client = new HttpClient())
        {
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials);


            var patchValue = new StringContent(JsonConvert.SerializeObject(patchDocument), Encoding.UTF8, "application/json-patch+json");

            var method = new HttpMethod("PATCH");
            var request = new HttpRequestMessage(method, "https://example.visualstudio.com/exampleproject/_apis/wit/workitems/$Support&20Ticket?api-version=1.0") { Content = patchValue };
            var response = client.SendAsync(request).Result;


            if (response.IsSuccessStatusCode)
            {
               var result = response.Content.ReadAsStringAsync().Result;

            }

 }}}} 

In the url for the PATCH I am using the team project's ID (in place of /exampleproject you see below). Our site is set up to have an overall project, let's call it ""Master", and inside is a team project for each client, for example "ClientProject". So basically I want to create a "Support Ticket" work item in Master->ClientProject->Backlog/Board.

Answer 1

The method must be POST and Uri correct for consume the Api tfs is :

https://dev.azure.com/{organization}/{proyect}/_apis/wit/workitems/${type}?api-version=5.0

Check in :

https://docs.microsoft.com/en-us/rest/api/azure/devops/wit/work%20items/create?view=azure-devops-rest-5.0

The next code function for me.

 static void Main(string[] args)
    {
        CreateWorkItem();
    }


    public static void CreateWorkItem()
    {
        string _tokenAccess = "************"; //Click in security and get Token and give full access https://azure.microsoft.com/en-us/services/devops/
        string type = "Bug";
        string organization = "type your organization";
        string proyect = "type your proyect";
        string _UrlServiceCreate = $"https://dev.azure.com/{organization}/{proyect}/_apis/wit/workitems/${type}?api-version=5.0";
        dynamic WorkItem = new List<dynamic>() {
                new
                {
                    op = "add",
                    path = "/fields/System.Title",
                    value = "Sample Bug test"
                }
            };

        var WorkItemValue = new StringContent(JsonConvert.SerializeObject(WorkItem), Encoding.UTF8, "application/json-patch+json");
        var JsonResultWorkItemCreated = HttpPost(_UrlServiceCreate, _tokenAccess, WorkItemValue);
    }


    public static string HttpPost(string urlService, string token, StringContent postValue)
    {
        try
        {
            string request = string.Empty;
            using (HttpClient httpClient = new HttpClient())
            {
                httpClient.DefaultRequestHeaders.Accept.Clear();
                httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "", token))));
                using (HttpRequestMessage httpRequestMessage = new HttpRequestMessage(new HttpMethod("POST"), urlService) { Content = postValue })
                {
                    var httpResponseMessage = httpClient.SendAsync(httpRequestMessage).Result;
                    if (httpResponseMessage.IsSuccessStatusCode)
                        request = httpResponseMessage.Content.ReadAsStringAsync().Result;
                }
            }
            return request;
        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message);
        }
    }

Answer 2

Using Master\\areapath instead (not Master\areapath).

Sample body:

[
  {
    "op": "add",
    "path": "/fields/System.Title",
    "value": "PBIAPI2"
  },
  {
    "op": "add",
    "path": "/fields/System.AreaPath",
    "value": "Scrum2015\\SharedArea"
  }
]

On the other hand, it’s better to create work item by using VSTS/TFS API with Microsoft Team Foundation Server Extended Client package.

Simple sample code:

var u = new Uri("https://[account].visualstudio.com");
            VssCredentials c = new VssCredentials(new Microsoft.VisualStudio.Services.Common.VssBasicCredential(string.Empty, "[personal access token]"));
           var connection = new VssConnection(u, c);

var workitemClient = connection.GetClient<WorkItemTrackingHttpClient>();
var workitemtype = "Product Backlog Item";
            string teamProjectName = "Scrum2015";
            var document = new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchDocument();
            document.Add(
    new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation()
    {
        Path = "/fields/Microsoft.VSTS.Common.Discipline",
        Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Add,
        Value = "development"
    });
            document.Add(
                new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation()
                {
                    Path = "/fields/System.Title",
                    Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Add,
                    Value = string.Format("{0} {1}", "RESTAPI", 6)
                });
            document.Add(new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation()
            {
                Path = "/fields/System.AreaPath",
                Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Add,
                Value =string.Format("{0}\\{1}",teamProjectName, "SharedArea")
            });
            document.Add(
                new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation()
                {
                    Path = "/fields/System.AssignedTo",
                    Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Add,
                    Value = "[user account]"
                });
            document.Add(
                new Microsoft.VisualStudio.Services.WebApi.Patch.Json.JsonPatchOperation()
                {
                    Path = "/fields/System.Description",
                    Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Add,
                    Value = "destest"
                });
var workitem= workitemClient.CreateWorkItemAsync(document, teamProjectName, workitemtype).Result;
