household.archived
A stored household was archived (DELETE).
Headers
Stable across retries of one event to one endpoint; deduplicate on it.
Unix seconds at this attempt (fresh on each retry); reject stale timestamps on your side.
'sha256=' + hex(HMAC-SHA256(secret, ${timestamp}.${rawBody})).
For 24 hours after a secret rotation: the same signature under the previous secret.
Payload
Response
Receipt. Any non-2xx (or a redirect, or a 5-second timeout) is a failed attempt, retried up to five more times with backoff. An event's first failed attempt counts toward auto-disable — 10 consecutive failed events disable the endpoint; any successful delivery resets the count.
Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
