Webhook Events
External post created event
Fired when Zernio's background sync detects a natively-authored post (created outside Zernio, e.g. a Google Business Profile localPost made in the Google UI) for the first time. Poll-driven (~hourly), not real-time. post.source is always "external".

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.
