Webhook Event Log

Overview

A Webhook Event Log is an append-oriented record of webhook events and delivery metadata, including event identity, timestamps, payload reference, signature result, attempts, acknowledgements, processing status, and errors. It differs from a general webhook log when it serves as an authoritative operational history for replay, investigation, and reconciliation.

The main risks include sensitive payload exposure, missing attempt records, mutable history, incomplete correlation, and retention too short for disputes. Business actions triggered by Webhook Event Log should be idempotent and should verify the current object state before fulfillment or accounting updates.

In production, teams should define ownership and apply immutable or tamper-evident records, payload access controls, event IDs, attempt history, retention policy, search indexes, and redaction. Monitoring for Webhook Event Log should track delivery age, signature failures, duplicate rate, retry exhaustion, and unresolved business events.

Useful measures include event completeness rate, log ingestion delay, missing payload count, replay retrieval time, and retention compliance. Webhook Event Log is closely connected to Webhook Log, Webhook Replay, and Delayed Webhook.

Recovery for Webhook Event Log should combine replay controls with an authoritative status check rather than trusting delivery history alone. A Webhook Event Log handler should acknowledge only after durable receipt when the provider’s retry contract depends on the response.

Replay of Webhook Event Log should preserve original identifiers and timestamps so historical processing cannot masquerade as a new event. For Webhook Event Log, 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 Event Log.
