Fires once per reopen: an analyst reopened a finalized credit memo to edit it. The final PDF it points at is kept and unchanged, but the memo is under revision until the next memo.finalized, so mark your copy stale. The payload carries ids, not the memo.
Signature over the exact request body: t=<seconds since the Unix epoch>,v1=<lowercase hex HMAC-SHA256 of "{t}.{body}" keyed with your endpoint's signing secret>. Verify it before trusting the body, and reject a t more than five minutes from your own clock. During a secret rotation both the new and the previous secret verify for 24 hours; each delivery is signed with exactly one.
The event id, identical to the body’s id. Stable across retries and replays, and shared by every endpoint one event fans out to. Delivery is at-least-once, so dedupe on it.
Event id: evt_ plus 24 lowercase hex characters. Also sent as the SpreadSpace-Event-Id header. Stable across retries and replays, so dedupe on it.
Seconds since the Unix epoch at which the event was created server-side. Seconds, not milliseconds. Deliveries are not ordered; reconcile on this.
true for live activity, false for test mode (an ss_test_ key or the sandbox simulator). Branch on it to route test deliveries to a staging handler.
The data object on a memo.reopened delivery, sent once per
reopen: an analyst reopened a finalized credit memo to edit it. The lock is
cleared and the final PDF the finalize made is KEPT, but the memo is under
revision until the next memo.finalized, so a receiver holding a copy
should mark it stale.
A pointer, not a payload: ids and the time only, never the memo’s prose.
The PDF that was in force is still pulled through
