Cloning Git Repo using TFS Personal Access Token

Question

I am trying to programmatically clone a git repository. My ASP.NET MVC application is creating and starting a process. The code to handle the processes works correctly however the authentication is failing when trying to use a TFS on premise PAT to clone a git repository. I cannot use NTLM or require the user to enter credentials. I can confirm my C# code handling creating processes to use the git bash shell programmatically works as I have no issue on my local machine but in production on IIS the issue arises. I have tried the following two methods.

Method 1: git clone http://anyusername:PAT@tfs2017:8080/tfs/DefaultCollection/_git/Git%20Repository

PAT is the token I have generated for my user. I have tried to encode it in base64 as well.

Method 2: As suggested by a person on a MS social forum.

git -c http.extraheader="AUTHORIZATION:bearer {base64encodedPAT}" clone {url}

Answer 1

If you have a PAT, you should not need a password: the PAT would act as your username.
See if the following works:

git clone http://PAT@tfs2017:8080/tfs/DefaultCollection/_git/Git%20Repository
