webhook_endpoint_not_configured
This tenant has no webhook endpoint yet (PUT /v1/webhook-endpoint creates it).
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
