Replay and DLQ

Replay and DLQ behavior are defined in sealed contracts.

Canonical sources:

  • Replay contract: docs/contracts/v1/webhooks/rc81/replay_contract_v1_3.md
  • DLQ rules: docs/contracts/v1/webhooks/rc93/dlq_rules_v1.md
  • DLQ format: docs/contracts/v1/webhooks/rc93/dlq_format_v1.md

Normative Requirements​

  • Replay should be used to recover from missed deliveries without creating duplicate side effects.
  • Receivers should treat replays the same way as normal deliveries (signature verification + deduplication).
