Webhook Events

External post updated event

Fired when a tracked native post's text or media changed on the platform. Detected by comparing text/media structure and, where available, the platform's own edit timestamp; a media-URL-only refresh does not fire this.

UTC time at which Zernio generated this event (set once when the event payload is built, before delivery is queued). Retries and redeliveries keep the original value, so it reflects the event, not the delivery attempt.

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.
