To verify Replicate webhook signatures in Next.js, you must handle the raw request body to compute the signature correctly. This process checks timestamp freshness and validates the payload to prevent replay attacks on your endpoint.

Handling Replicate prediction status events in an Express webhook endpoint involves parsing payload statuses like start, processing, output, and completed. You can trigger downstream actions based on these status-driven events for real-time updates.

Yes, you can use FastAPI to receive and validate Replicate webhooks. The framework supports raw body handling necessary for accurate signature verification, ensuring your prediction event processing remains secure and reliable.

Replicate webhook signature verification fails without raw body handling because modifying the request body alters its hash. You must maintain the original raw payload to accurately compute and validate the webhook signature against the incoming request.

The best way to prevent replay attacks on Replicate webhook endpoints is to enforce timestamp freshness checks during validation. This ensures that intercepted webhook payloads cannot be resent and processed after a specified time window.
