What you get with this Offer
I will build a production-ready webhook receiver for your specified webhook source — covering HTTPS endpoint creation, signature verification (HMAC-SHA256 or provider-specific), immediate 200 acknowledgement with async processing, idempotency key storage for duplicate event detection, payload validation, and structured logging for debugging and audit. Webhook endpoints that process events synchronously before returning 200 fail under load because the sending system's timeout is reached before processing completes, causing retry storms that create exactly the duplicate processing that idempotency handling is designed to prevent — async processing with immediate acknowledgement is the correct pattern.
The receiver covers HTTPS endpoint with SSL, provider-specific signature verification, immediate 200 response with async queue submission, idempotency key database storage, payload schema validation, and structured event logging.

What the Freelancer needs to start the work
Please share your webhook source documentation (signature method, payload schema, retry policy), your backend language and framework, your database for idempotency storage, and your processing logic requirements.
