I am trying to verify our HTTPS endpoint for Marketplace Account Deletion notifications, but the eBay Developer Portal does not verify the endpoint — and we see no incoming request.
✅ Our webhook is public, uses a valid Let's Encrypt SSL cert, and is production-ready:
Endpoint URL: https://vimenova.com/webhook/ebay-notification
✅ The endpoint returns HTTP 200 with the correct JSON format:
{ "challengeResponse": "<sha256-hash>" }
✅ We’ve tested this using curl and confirmed n8n handles the challenge correctly.
❌ However, when we click "Verify Endpoint" in the eBay Developer Portal, **no request is received**, and no logs appear in n8n.
Please verify whether your systems are sending the challenge request and confirm if there are any known issues or delays.
Developer Username: discountedlistings0515
Verification Token: vimenovaebayverification123456789
We’re trying to complete compliance with the Marketplace Account Deletion Notification requirement.
