List signals

The club's signal history, oldest first — one record per thing that happened. This is the recovery path. If your endpoint was offline, replay the window with created_after / created_before and reconcile; you get the stored copy exactly as it was delivered, never a re-render of current state.

Narrow with type (one exact signal type) or resource_id (everything about one resource). Cursor-paginate via starting_after.

Reading the most recent instead. The default order is ascending, so page one is the club’s OLDEST signals — replaying forward is what recovery needs. Pass order=desc when you want the latest N and would otherwise have to page through the entire history to reach them. starting_after follows whichever order you asked for.

You see a filtered view. A signal whose required scope your key lacks is simply absent — not an error. That, plus any type or resource_id filter you pass, is why sequence gaps are normal and mean nothing. A webhook endpoint’s subscribed types do not filter this list.

Membership limitation. subscription.* signals cover memberships on the subscription billing engine. A club still on the legacy membership model emits none of them — the absence is expected, not a fault. Ask the club which model it is on before wiring a membership automation.
