Webhook Events

Post platform failed event

Fired once per platform target inside a post as that platform fails permanently. Temporary/retryable failures do NOT fire this event, only permanent ones do, so retry loops stay quiet. The envelope event (post.failed / post.partial) fires separately AFTER all platforms have terminated. Can also fire a second time for a target that already emitted post.platform.published, if background reconciliation later discovers the publish never actually completed.

postWebhookpost.platform.failed

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.platform.published' | 'post.platform.failed' | 'post.platform.deleted' | 'post.tiktok.url_resolved' 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.
