GitHub Webhook
GitHub Webhook is a feature that allows GitHub to send HTTP POST requests to a specified URL when certain events occur in a repository. These events can include code pushes, pull requests, issues, releases, and more. Webhooks enable external services, such as Jenkins or CI/CD systems, to be notified automatically when changes or events happen in a GitHub repository.
To set up a webhook in a GitHub repository:
In your GitHub repository, go to "Settings", navigate to "Webhook", and click on "Add Webhook"
Provide the Payload URL: Add the Jenkins URL to the field labelled "Payload URL", then add "/github-webhook" to the end of the URL.
Choose the events you want to trigger the webhook.
Add the webhook.
