VSTS Create New WorkItem

Question

I am using the VSTS REST API and I am trying to create a new WorkItem. But I can get the existing WorkItem from VSTS and update the WorkItem.

        var listDoNotUpdate = new List<string>();
        listDoNotUpdate.Add("System.BoardColumn");
        listDoNotUpdate.Add("System.BoardColumnDone");
        var wi = await this.Client.GetWorkItemAsync(4000);
        wi.Fields["System.Title"] = "Test";
        wi.Fields["System.Description"] = "Test";
        wi.Fields["Microsoft.VSTS.Common.AcceptanceCriteria"] = "Test";
        var doc = new JsonPatchDocument();
        foreach (var field in wi.Fields)
        {
            if (!listDoNotUpdate.Contains(field.Key))
            {
                doc.Add(new JsonPatchOperation
                {
                    Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Replace,
                    Path = string.Concat("/fields/", field.Key),
                    Value = field.Value
                });
            }
        }

        await this.Client.UpdateWorkItemAsync(doc, 4000);

But how can I create a new WorkItem and load it?

Answer 1

They seem to have forgotten the CreateWorkItemAsync method. All other update methods have a corresponding Create method. To create a work item, you can use the following snippet

var client = new RestClient(string.Format(
    CultureInfo.InvariantCulture,
    "https://{0}.visualstudio.com/defaultcollection/{1}/_apis/",
    "<vstsAccount>",
    "<project>"));
client.Authenticator = new HttpBasicAuthenticator("accessToken", "<accessToken>");
var json = @"[{'op': 'add','path': '/fields/System.Title','value': 'Title of your work item'}]";
var request = new RestRequest("wit/workitems/$Product Backlog Item?api-version=1.0", Method.PATCH);
request.AddParameter("application/json-patch+json", json, ParameterType.RequestBody);
request.AddHeader("Accept", "application/json");
var response = client.Execute(request);

The response will contain json of the new work item. Use it to retrieve the id of the new item.

You're close Instead of calling UpdateWorkItemAsync, you need to call UpdateWorkItemTemplateAsync.

var collectionUri = "https://{account}.visualstudio.com";
var teamProjectName = "{project}";
var workItemType = "{workItemType}";
var client = new WorkItemTrackingHttpClient(new Uri(collectionUri), new VssClientCredentials());

var document = new JsonPatchDocument();
document.Add(
    new JsonPatchOperation()
    {
        Path = "/fields/System.Title",
        Operation = Microsoft.VisualStudio.Services.WebApi.Patch.Operation.Add,
        Value = "Title"
    });

var wi = client.UpdateWorkItemTemplateAsync(
    document,
    teamProjectName,
    workItemType).Result;
