GitHub's webhooks documentation is a comprehensive resource that excels in many areas, particularly signature verification and troubleshooting failure recovery. The documentation provides detailed explanations of the signature scheme and code samples for verifying signatures, as well as instructions on how to troubleshoot common issues. The event catalog is extensive, listing every available event type with sample payload schemas and descriptions. However, the retry policy could be improved by providing automatic retries, which are currently only documented thoroughly but not implemented. The documentation also includes testing tools, such as articles on testing webhook deliveries and local testing using smee.io or GitHub CLI. Overall, the documentation is well-written, informative, and easy to navigate, making it an excellent resource for developers.
