Finta Webhooks & Events

Overview

Process integration events safely by authenticating the sender, minimizing payload handling, and making every downstream action replay-safe.

Prerequisites

• A verified signing-secret delivery path and a service that can retain the raw request body for verification.
• A durable event ledger or idempotency store plus an exception-queue owner.
• Synthetic event fixtures and an approved destination allowlist.

Instructions

1. Verify the signature and timestamp before parsing or queuing an event.
2. Store only opaque event identifiers and necessary state; redact payloads from diagnostics.
3. Deduplicate by provider event ID, queue approved work with bounded retries, and acknowledge only after durable acceptance.
4. Route unknown event types, signature failures, and exhausted retries to reviewed handling without replaying side effects.
