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: the dedupe key, also sent as the X-Zernio-Event-Id header and identical on every retry and redelivery. It identifies the event only, never an account or other resource.

testboolean

Always true when present: only a sample sent by POST /v1/webhooks/test with an event carries it. Real deliveries never do.

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.

Example payload

{
  "profiles": [
    {
      "externalId": "tenant_42"
    }
  ]
}

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.
