Who is this workflow for? This n8n workflow enables you to monitor multiple GitHub repositories efficiently using webhooks, eliminating the need for constant polling. It allows you to add or remove repositories from your watchlist programmatically, streamlining repository management and ensuring real-time notifications..

What does this workflow do?

  • Creating GitHub Credentials:
  • Generate a personal access token on GitHub with the required scopes (admin:repo_hook and repo for private repositories).
  • Follow GitHub’s instructions to create the token: GitHub Docs.
  • Setting Up Credentials in n8n:
  • In the Register GitHub Webhook node, configure authentication using a Generic Credential Type with Header Auth.
  • Create a new credential named Authorization and set its value to Bearer <YOUR GITHUB TOKEN HERE>.
  • Apply this credential to the Delete GitHub Webhook and Get Existing Webhooks nodes as well.
  • Update the url field in the webhook JSON body to match the Production URL from the Webhook Trigger node.
  • Configuring Notification Settings:
  • Link the Webhook Trigger node to your preferred notification API, such as Slack or Telegram.
  • Customize the notification messages to fit your team’s requirements.
  • Registering Webhooks:
  • Add repositories to the Repos to Monitor list.
  • Disable the Webhook Trigger node and click Test Workflow to register webhooks automatically.
  • Verify webhook registration by running the Get Existing Webhook node to confirm repository addresses.
  • Handling GitHub Events:
  • Re-enable the Webhook Trigger node and activate the workflow.
  • Make a commit or perform an action in any monitored repository.
  • Confirm that the configured notification is received, indicating successful event handling.
