A webhook gateway is a tool that manages the flow of webhook events between providers and consumers, offering features such as reliable delivery, routing, security, and scalability. Convoy, an open-source webhook gateway, provides solutions for common challenges like failed webhook deliveries due to factors like network issues or expired SSL certificates, by implementing retries, circuit breaking, rate limiting, and timeouts. It facilitates routing in microservices and integrates with message brokers like Google PubSub and Amazon SQS to handle asynchronous communications, providing static IPs for secure connections. Additionally, Convoy offers monitoring, alerts, and a user-friendly interface for debugging, and supports geolocation-based routing and versioning to accommodate evolving API signatures. By enabling these capabilities, Convoy helps platform teams manage webhooks efficiently without needing deep involvement from developers in the webhook implementation, allowing them to focus on core business products.
