# creator_campaign.closed

A campaign closed, either because you closed it or because `endsAt` passed.

### When it fires

After `endsAt`, the campaign closes once every tracking window had its final read. A pool campaign is split among participants at this moment.




**Payload for `creator_campaign.closed`:**

- **id** (required) `string`: 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.
- **profiles**: `WebhookProfiles` - See schema definition
- **test** `boolean`: Always true when present: only a sample sent by POST /v1/webhooks/test with an event carries it. Real deliveries never do.
- **event** (required) `string`: No description - one of: creator_campaign.budget_exhausted, creator_campaign.closed
- **campaign** (required) `object`: 
  - **id** (required) `string`: No description
  - **name** (required) `string`: No description
  - **budgetCents** (required) `integer`: No description
  - **budgetExhaustedAt** `string` (date-time): Present on creator_campaign.budget_exhausted only.
  - **closedAt** `string` (date-time): Present on creator_campaign.closed only.
- **timestamp** (required) `string` (date-time): 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.
