FastAPI Webhooks in Python: Handle Long-Running LLM Jobs

About this lesson

Stop polling long LLM jobs—use a FastAPI webhook receiver to accept async results, verify signatures, and update job state reliably. Build a secure, idempotent flow that replaces polling, ensures durable SQLite-backed job records, and keeps dashboards and downstream tasks consistent. Hands-on with FastAPI, Python, HMAC-SHA256 signature verification, idempotent state machines, and simple SQLite persistence you can map to production.
