Live Activity webhook

People search for a “Live Activity webhook” expecting Apple to call their server when a Live Activity changes. That is not how ActivityKit works.

Apple does not POST activity events to you. Your server pushes to APNs. The iPhone is the subscriber. If you need your own systems to react (for example a courier GPS service), that webhook is between your services — then you call APNs (or Live Hive) to update the device.

Live Hive is an HTTP API you call, not a webhook you expose. See getting started.
