Adding Entra Group as Repository Administrator via API

API Endpoint:

POST https://dev.azure.com/{organization}/_apis/accesscontrolentries/2e9eb7ed-3c0a-47d4-87c1-0ffdd275fd87?api-version=7.1

Request Body:

{
 "token": "repoV2/{projectId}/{repositoryId}",
 "merge": true,
 "accessControlEntries": [
 {
 "descriptor": "aadgp.{entraGroupObjectId}",
 "allow": 8188,
 "deny": 0
 }
 ]
}

Key Details:

• Security Namespace ID: 2e9eb7ed-3c0a-47d4-87c1-0ffdd275fd87 (Git repositories)

• Token format: repoV2/{projectId}/{repositoryId}

• Descriptor format: aadgp.{entraGroupObjectId}

• Admin permissions value: 8188 (includes all repository admin rights)

Requirements:

• PAT token with "Project and Team (read, write, & manage)" permissions

• Entra group Object ID from Azure AD

• Project and Repository GUIDs

Verification: After the API call, the group will appear in: Project Settings → Repositories → {repository-name} → Security tab with Administrator permissions.

The changes typically reflect in the UI within a few minutes.
