About repository webhooks
Repository webhooks allow you to receive HTTP POST payloads whenever certain events happen in a repository. You can use the REST API to manage repository, organization, and app webhooks. You can list webhook deliveries for a webhook, or get and redeliver an individual delivery for a webhook, which can be integrated into an external app or service. You can also use the REST API to change the configuration of the webhook. For example, you can modify the payload URL, content type, SSL verification, and secret. For more information, see:
