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".

postWebhookpost.external.created

Payload

idstring required

Stable webhook event ID

event'post.external.created' | 'post.external.updated' | 'post.external.deleted' required

timestampstring date-time required

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.
