Hello,

I am facing the same issue and I am using the following for the git-credentials REST api from postman
1) databricks PAT for authorization bearer token
2) personal_access_token = Azure Devops PAT
3) git_username = Service Principal display name (This is the owner/ Run-as on my databricks workflow and it needs to access notebooks from my Azure DevOps repo)
4) git_provider = azureDevOpsServices.

Questions:
1) Where am I going wrong while using the API?
2) When I choose Azure DevOps Services AAD authentication for the service principal, why doesn't the Databricks - Azure Devops (ADO) integration work without having to work with PATs?
The reason for using a service principal is, I don't want my personal ADO PAT to be used for any configuration.
Plus, service principals can't have PATs in ADO. (Another reason why SPNs are used and are more secure)
The service principal has access to both databricks workspace and ADO repo
