VALIDATION_ENDPOINT_UNREACHABLE

The webhook endpoint did not accept a test delivery.

HTTP status: 422. Retrying the same request returns the same error.

What to do

Check the error message and fix the endpoint. Then reactivate it with PATCH /v2/webhooks/:webhookId and the body { "status": "active" }.

Hint returned with the error: Make sure the endpoint responds with a 2xx status to a signed POST request, then try again.

Why it happens

  • Reactivating a webhook endpoint that still fails (Pyas sends a test delivery first)
  • The endpoint is down, responds with a non-2xx status, doesn't respond within 10 seconds, or resolves to a private network

Endpoints that return it
