Garth integrates with Azure DevOps to deliver:
  • Instant code reviews on active pull requests.
  • Actionable inline suggestions on every diff.
  • Smooth alignment with standard Azure enterprise workflows.

​
Step 1: Create the integration account

Create a dedicated Azure DevOps service account for Garth rather than binding the integration to a personal staff account.
1

Register the account

Log out of your personal Azure DevOps account and create a new user specifically for this integration.
2

Finalize the profile

  • Set the username to something identifiable, such as GPRABot. - Use a team alias email rather than a personal address. - Enable Two-Step Verification (2FA) if required by your company policy.
3

Associate with your organization

Add the new service account to your primary Azure DevOps organization and the projects you want Garth to analyze.
The PAT account must have the Project Administrators role on every project you want to integrate. Without it, repository installation and webhook setup will fail.
When you rotate the service account later, update the token in Garth and re-enable repository tracking — no other reconfiguration is needed.

​
Step 2: Create a Personal Access Token (PAT)

1

Authenticate as the service account

Ensure you are logged into Azure DevOps using the dedicated Garth service account.
2

Open security settings

Navigate to Edit Profile and select Personal access tokens.
3

Create the token

Click New token and give it a descriptive name such as Garth PR Token.
4

Set the expiration

For production use, set the expiration to 1 year.
5

Select token scopes

Grant exactly the following permissions:
6

Save the token

Copy the token immediately after generation — Azure DevOps displays it only once. Store it in a secure location.
1

Open Garth integrations

Log into the Garth dashboard and navigate to Settings → Integrations.
2

Bind the token

Select the Azure DevOps tab. Enter your Azure DevOps URL (https://dev.azure.com/your-organization), Username (the service account’s email), and Personal Access Token, then click Validate.

Enter your Azure DevOps URL, username, and Personal Access Token, then click Validate

Install repositories

After validation, select the repositories you want Garth to review and click Install Repositories.
Automatic webhooks: Garth installs webhooks on selected Azure DevOps projects automatically. No manual webhook configuration is required. Webhooks are also removed automatically when you uninstall a repository.

​
Step 4: Activate and configure the repository

After installation, activate each repository under Agent Setup → PR Review → Repository Setup. Once a repository is activated, you can configure the following options:
  1. Files to Exclude — specify file patterns that Garth should skip during reviews.
  2. Source Branches to Exclude — exclude PRs originating from certain branches.
  3. Destination Branches to Exclude — exclude PRs targeting certain branches.
  4. Auto Review — enable or disable automatic reviews for new PRs on this repository.
  5. Repository PR Review Guidelines — define custom review guidelines specific to this repository.

​
Troubleshooting

If Garth is not accessing repositories or reviewing pull requests:
  1. Check webhook status — go to your Azure DevOps project settings under Service Hooks and verify the Garth webhook exists and is active.
  2. Manually delete the webhook if it exists but is not working.
  3. Refresh the repository page in the Garth app.
  4. Reinstall the webhook — untoggle and re-toggle the repository in the Garth dashboard.
If you cannot install Garth on a repository:
  1. Verify permission levels — the service account must hold Project Administrator or Project Collection Administrator permissions.
  2. Check token scopes — confirm the PAT includes Code: Read & Write and Work Items: Read capabilities.
  3. Re-validate the token — go to Settings → Integrations → Azure DevOps in Garth and re-enter your credentials.
  4. Toggle the repository — uninstall and reinstall the repository from the Garth app to force a fresh webhook setup.
If Garth is installed but you are not receiving any reviews on your pull requests:
  1. Check repository activation — go to Agent Setup → PR Review → Repository Setup and confirm the repository is activated.
  2. Verify Auto Review is enabled — ensure the Auto Review toggle is turned on for the repository.
  3. Check branch exclusions — confirm the source or destination branch of your PR is not listed under Source Branches to Exclude or Destination Branches to Exclude.
  4. Check file exclusions — verify that the files changed in your PR are not covered by patterns in Files to Exclude.
If you receive authentication or permission errors:
  1. Check token expiry — Azure DevOps PATs expire based on the timeframe you set; regenerate and update the token in Garth if it has lapsed.
  2. Confirm Entra ID is enabled — your organization must have Entra ID (formerly Azure Active Directory) active for the integration to function.
  3. Verify Microsoft App Consent — confirm your IT administrator has approved the Garth application in the Microsoft consent portal if administrative approval is required.
  4. Re-authenticate — update the PAT in Settings → Integrations → Azure DevOps within Garth and re-link with a freshly generated token.
