Safety checklist before replay

  • Root cause is fixed (credentials, endpoint, provider outage).
  • Destination can handle duplicate payloads safely.
  • You have audit context for why replay is being executed.

Replay workflow

1. Locate message

Open Activity and select the message.

2. Trigger replay

Use replay action for that message.

3. Validate result

Confirm a new delivery record succeeds and destination receives expected payload.

Avoiding duplicate side effects

[!WARNING] Use idempotency controls on downstream systems when actions are non-reversible.
