The Challenge
High-volume webhooks from social networks and third-party CRM systems arrive in volatile bursts. Processing these webhooks synchronously results in timeouts and connection limits, while out-of-order execution ruins transactional workflows and conversation context.
The Solution
We developed an event-driven webhook gateway that ingests payloads instantly, writes them to a partitioned stream, and guarantees FIFO (First-In, First-Out) execution per customer channel. It integrates with AI model dispatch layers to process context-aware replies asynchronously.
System Architecture
The gateway is written in Go, acting as a lightweight proxy. It writes incoming requests directly to a Redis Stream with partition keys. Python/FastAPI workers consume the stream, executing business logic and calling external LLM APIs asynchronously while maintaining strict transaction logs.
