In this context, APIs have limitations, such as making multiple API calls which can waste bandwidth and resources. Webhooks provide an event-driven approach to simplify this problem by sending automated notifications to other applications in response to designated events, eliminating the need for repeated API calls. To ensure a secure experience with webhooks, developers should consider authentication measures, sign their webhook payload with a secret key or signature, encrypt data sent by webhooks, authenticate connections and use certificate pinning, handle non-sensitive data, implement error handling and retry policies, and implement logging to monitor activity. By following these best practices, developers can achieve security, scalability, and ease of implementation while minimizing bandwidth usage and manual oversight.
