Webhook Acknowledgement

Overview

Webhook Acknowledgement is the receiver response that tells the sender a delivery attempt was accepted according to the webhook contract. Acknowledgement confirms delivery acceptance, not necessarily completion of all downstream business processing, so the receiver should persist the event before responding when loss would be harmful.

The main risks include acknowledging before persistence, slow synchronous work, false success responses, repeated retries, and event loss after process failure. It is usually an HTTP success status and may require a specific response body. Recovery for Webhook Acknowledgement should combine replay controls with an authoritative status check rather than trusting delivery history alone.

In production, teams should define ownership and apply fast response path, durable event persistence, contract-compliant status and body, signature validation, idempotency, and timeout monitoring. A Webhook Acknowledgement handler should acknowledge only after durable receipt when the provider’s retry contract depends on the response.

Useful measures include acknowledgement latency, non-success response rate, retry-trigger rate, persistence-before-ack rate, and acknowledgement timeout count. Webhook Acknowledgement is closely connected to Webhook Handler, Failed Webhook, and Webhook Event Log. Monitoring for Webhook Acknowledgement should track delivery age, signature failures, duplicate rate, retry exhaustion, and unresolved business events.

Replay of Webhook Acknowledgement should preserve original identifiers and timestamps so historical processing cannot masquerade as a new event. For Webhook Acknowledgement, the event identifier, signature result, delivery attempt, and resulting business state should remain connected throughout processing. A receiver should treat transport acknowledgement and successful downstream processing as separate states for Webhook Acknowledgement.

The Webhook Acknowledgement path should preserve ordering and duplicate evidence so delayed delivery cannot silently overwrite a newer state.
