Response Expected

The merchant’s webhook endpoint must return HTTP 200 (OK) to confirm that the notification was successfully received and processed. If Bamboo receives any other status code or no response, the notification will be retried according to the Retry Policy.

Response Code	Meaning
`200`	Notification successfully received and processed.
`4xx`	Client-side error (invalid endpoint, payload rejection, or failed signature validation).
`5xx`	Temporary server error. Bamboo will retry the notification automatically.
