# Post failed event

`POST post.failed` (webhook)

Fired when a post fails to publish on all target platforms.

## Payload

- WebhookPayloadPost — Webhook payload for post events
  - `id` string, required — Stable webhook event ID
  - `event` 'post.scheduled' | 'post.published' | 'post.failed' | 'post.partial' | 'post.cancelled' | 'post.recycled', required
  - `post` object, required
    - `id` string, required
    - `content` string, required
    - `status` string, required
    - `scheduledFor` string, date-time, required
    - `publishedAt` string, date-time
    - `platforms` object[], required
      - `platform` string, required
      - `status` string, required
      - `accountId` string — SocialAccount id this platform target published through. Use it to route events by connected account (e.g. separate staging vs production endpoints). A post can span multiple accounts.
      - `platformPostId` string
      - `publishedUrl` string
      - `error` string
    - `metadata` object — The free-form `metadata` object supplied when the post was created, echoed back so you can map events onto your own records. Omitted when the post was created without it.
  - `timestamp` string, 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.
