# Brief published

`POST brief.published` (webhook)

A brief reached its creators: created or updated with a notification to them (`created`, `updated`), or newly reaching creators without a new version (`assigned`: linked to a campaign, sent to creators directly, or shared with everyone at the organization). Saves without a notification that reach nobody new are not reported.

## Headers

- `webhook-id` string, required
- `webhook-timestamp` string, required
- `webhook-signature` string, required

## Payload

- BriefPublishedWebhookEvent: A brief reached its creators: created or updated with a notification to them (`created`, `updated`), or newly reaching creators without a new version (`assigned`: linked to a campaign, sent to creators directly, or shared with everyone at the organization). Saves without a notification that reach nobody new are not reported.
  - `id` string, required: Event id; the `webhook-id` header. The same on every retry: dedupe on it.
  - `type` 'brief.published', required
  - `timestamp` string, date-time, required: When the change happened
  - `organizationId` string, required
  - `actor` WebhookActor, required: Who caused the event: a member (`user`), an API key (`apiKeyId`), a creator, or viral.app itself (`system`); `surface` says where the change entered. Skip events your own API key caused to avoid loops.
    - `type` 'user' | 'api_key' | 'creator' | 'system', required
    - `surface` 'ui' | 'api' | 'copilot' | 'system', required
    - `userId` string, nullable, required
    - `apiKeyId` string, nullable, required
    - `impersonated` boolean, required
  - `data` object, required
    - `brief` WebhookBrief, required
      - `id` string, required
      - `name` string, required
      - `version` integer, required
      - `campaignIds` string[], required
      - `creatorIds` string[], required
      - `allCreators` boolean, required
      - `lastNotifiedAt` string, date-time, nullable, required
    - `kind` 'created' | 'updated' | 'assigned', required

## Acknowledgement `200`

Any 2xx within 15 seconds acknowledges the event. Anything else, a timeout or a redirect is retried (10 attempts over about 3 days); 410 disables the endpoint.
