  "type": "https://docs.digitalseaservice.com/errors/no_webhook_configured",
  "title": "Partner has no webhook URL or signing secret registered",
  "status": 409,
  "detail": "Register a webhook URL and rotate a signing secret before calling /v1/webhooks/test.",

​
What it means

GET /v1/webhooks/test fires a webhook.test event to your registered webhook URL, signed with your webhook signing secret. This 409 means one or both of those is missing — there’s nowhere to deliver the test event, or nothing to sign it with.

​
What to do

Register a webhook URL and rotate a signing secret first, then retry. In sandbox, email admin@digitalseaservice.com with your HTTPS URL; we return the signing secret and you’re ready to test. See Webhooks / registering.
