Webhook events
Webhook events
Every webhook event type Koast sends, with its payload fields and an example.
Each page lists the event envelope, the fields under data, an example payload generated from the schema, and the delivery headers.
| Event type | Description |
|---|---|
ad.approved | An ad passed the platform's review and is live or scheduled. |
ad.rejected | The platform rejected an ad. |
delivery.status_changed | A campaign, ad set or ad changed delivery status. |
launch.completed | A launch published every campaign, ad set and ad. |
launch.failed | A launch failed. |
launch.partially_failed | A launch published some entities and failed others. |
metrics.updated | Fresh totals for an ad account. |
ping | Only from a test send. |
spend.day_closed | An ad account's day ended, in its own timezone, with that day's spend. |
To receive them, create an endpoint and verify each delivery as the Webhooks guide explains.
