Answer 1

To access Azure DevOps via REST API, the Resource of the web activity should be 499b84ac-1321-427f-aa17-267ca6975798, which is the resource ID for Azure DevOps services. According to your screenshot, you are using a System-assigned managed identity for authentication. You should add this system-assigned managed identity into your DevOps organization, assign Basic access level and add it into Contributors group. Share my working steps for your reference.

1. Configure Web activity

   • Authentication: System-assigned managed identity

   • Resource: 499b84ac-1321-427f-aa17-267ca6975798

2. Find your ADF system-assigned managed identity

   Go your ADF -> Settings -> Properties -> Find and copy Managed Identity Application ID.

   

3. Add your ADF system-assigned managed identity into Azure DevOps organization via its Managed Identity Application ID. Assign it with Basic access level (Basic access level is required for accessing Azure Repo) and add it into Contributors group of your target project.
