Webhook Reliability

Reliable webhook delivery requires more than forwarding events. Zen Mesh provides operational controls for recovery, duplicate handling, and targeted routing.

Capabilities

Capability	Purpose
Dead Letter Queue	Preserve failed delivery attempts for inspection, recovery, and replay
Webhook Replay	Replay events from DLQ or delivery history for reprocessing
Webhook Deduplication	Identify and handle duplicate events with configurable dedup keys
Webhook Idempotency	Safe retry and duplicate processing with idempotency controls
Webhook Filtering	Route or suppress events according to configured conditions
Webhook Fan-Out	Deliver events to multiple destinations with per-destination policies
JSONPath Routing	Route webhooks with safe JSONPath filter and match rules
JSONPath Transforms	Map and reshape webhook payloads with JSONPath expressions

Architecture

All delivery capabilities operate within the Zen Mesh data plane. Events pass through:

1. Ingester — event intake, signature verification, filtering, deduplication
2. Delivery controller — routing, retry, DLQ management, fan-out
3. Egress — delivery to customer targets with per-destination policies
