How to connect TFS Online using PAT or OAUT?

Question

Can't believe I'm stuck with a LOGIN :( hate when this happens.

Can somebody enlight me how to connect TF.EXE by using PAT password or in the best case an OAuth token?

I might add that I already have a Pat token and an OAuth token, not a problem while trying to get those, but every time I try this example:

TF.exe workspaces /collection:xxxx.visualstudio.com/xxxx /loginType:OAuth /login:.,MyPatTokenOrMyOauthToken /noprompt

I get the following response:

TF30063: You are not authorized to access xxxx.visualstudio.com\xxxx.

So, I Know command it's ok, because if I don't specify a login, a modal window prompts for credentials, and I tested already with that approach and works fine.

For the end, I might change everything to change tf.exe for the TFS api, but I'm unable to find same methods in the api (see reference: https://learn.microsoft.com/es-es/rest/api/vsts/?view=vsts )

If API has same methods than TF.exe, that will be useful, but so far I don't see same methods in the API.

Hope somebody has the solution for my problem.

Thanks in advance.

From my test, PAT token doesn't work in the following command, you have to get a OAuth token:

tf workspaces /collection:https://xxxx.visualstudio.com /loginType:OAuth /login:.,[OAuth token]

For the api that authenticate with Visual Studio Team Services (VSTS), you could refer to the examples in this link:

Here is an example getting a list of projects for your account:

REST API

using System.Net.Http;
using System.Net.Http.Headers;

...

//encode your personal access token                   
string credentials = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "", personalAccessToken)));

ListofProjectsResponse.Projects viewModel = null;

//use the httpclient
using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("https://{accountname}.visualstudio.com");  //url of our account
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials); 

    //connect to the REST endpoint            
    HttpResponseMessage response = client.GetAsync("_apis/projects?stateFilter=All&api-version=1.0").Result;

    //check to see if we have a succesfull respond
    if (response.IsSuccessStatusCode)
    {
        //set the viewmodel from the content in the response
        viewModel = response.Content.ReadAsAsync<ListofProjectsResponse.Projects>().Result;

        //var value = response.Content.ReadAsStringAsync().Result;
    }   
}

.Net Client Libraries

using Microsoft.TeamFoundation.Core.WebApi;
using Microsoft.VisualStudio.Services.Common;

...

//create uri and VssBasicCredential variables
Uri uri = new Uri(url);
VssBasicCredential credentials = new VssBasicCredential("", personalAccessToken);

using (ProjectHttpClient projectHttpClient = new ProjectHttpClient(uri, credentials))
{
    IEnumerable<TeamProjectReference> projects = projectHttpClient.GetProjects().Result;                    
}

Update:

I've tested with a new account, and the result is as below. If I remove /loginType and /login parameters, a window will pop up to ask me logon.

As per 2023, the following snippet may help:

MY_PAT=yourPAT # replace "yourPAT" with "PatStringFromWebUI"

B64_PAT=$(printf ":%s" "$MY_PAT" | base64)

git -c http.extraHeader="Authorization: Basic ${B64_PAT}" clone https://dev.azure.com/yourOrgName/yourProjectName/_git/yourRepoName

as described in this link,

And you can get the "yourPAT" from this link
