Zoom's webhook documentation is comprehensive and well-structured, providing detailed explanations of signature verification, event catalog, retry policy, troubleshooting and failure recovery, and testing tools. The documentation excels in explaining the signature scheme and providing sample code in Node.js, earning an A grade for this section. While the event catalog lists every available event type with sample payload schemas, it could benefit from a direct link to the event catalog. The retry policy is described, but with room for improvement, particularly regarding the delay between retries. Troubleshooting and failure recovery are adequately covered, but additional guidance on recovering messages that should have been sent while the endpoint was failing would be beneficial. Testing tools are available, including the ability to send test messages and generate an endpoint URL. Overall, Zoom's documentation does a great job of explaining how to set up webhook notifications, but providing tools for testing and troubleshooting would further enhance the developer experience.
