The article provides a comprehensive guide on implementing webhooks using the Convoy service in a Go-based Todo API developed with the Gin HTTP Router Library. Webhooks are described as messages sent from an application after an operation, often used for communication between services, such as a payment provider sending events to an e-commerce application. The guide explains the process of setting up the API and Convoy to generate and send webhook events for operations on Todo items, including creating, updating, and deleting, with specific event types like "todo.created," "todo.updated," and "todo.deleted." The article includes detailed code examples and instructions for building the API, managing endpoints, and publishing webhook events, emphasizing best practices for production environments, such as scoping endpoints to users and using workers for event publication.
