Webhooks
Placement Updated
Fired when a placement record is updated, including when it is approved. The payload is a full snapshot of the placement, not a diff — compare it against the previously delivered event to see what changed. An approval shows as approved going from false to true.

Payload
Response
Return any 2xx status to acknowledge receipt of the webhook.
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.
