Server-Side Events (SSE) and webhooks are two distinct technologies used to manage real-time data and event-driven architectures, each with its own advantages in specific scenarios. SSE provides a unidirectional, persistent connection from server to client, ideal for streaming real-time updates such as risk scores or transaction feeds in fintech applications, leveraging the standard HTTP protocol for simplicity and efficiency. Webhooks, on the other hand, are client-initiated callbacks triggered by server-side events, useful for notifying clients about specific events like transaction settlements or fraud alerts, allowing them to take necessary actions. Both technologies can be combined to create a robust workflow bus, which requires careful attention to scalability, error handling, and security, employing best practices like message queues, robust error handling, and secure API design. Didit exemplifies the integration of these technologies by offering a comprehensive identity platform that utilizes SSE for real-time risk scoring and webhooks for event-driven workflows, providing scalable and reliable infrastructure to enhance fintech applications.
