Trying to submit my zoom app for review, but the verification of domain isnt working

App Marketplace Domain Validation
1

Hi everyone,

I’m currently preparing a Zoom OAuth Marketplace app for an event management platform called Ticket Deck (ticket-deck.com), and I’m running into an issue with domain verification.

The app uses:

  • Zoom OAuth user-level app

  • Supabase Edge Functions for OAuth handling

  • React/Vite frontend hosted through Lovable

  • HTTPS/TLS enabled

I’m trying to verify the domain using the HTML file method.

Zoom generated this file:
ZOOM_verify_b8d30634336f4b9588c7aae58a972085.html

The file has been added to the root/public directory and is accessible at:
https://ticket-deck.com/ZOOM_verify_b8d30634336f4b9588c7aae58a972085.html

When visiting the URL directly in the browser, it correctly displays only:
b8d30634336f4b9588c7aae58a972085

The app has also been republished/deployed after adding the file.

However, Zoom still returns:
“Domain verification failed.”

A few things I’d like to confirm:

  1. Does Zoom cache failed verification attempts for some time?

  2. Does the verification file need any specific content-type/header?

  3. Can Cloudflare/Lovable hosting affect Zoom’s verification crawler?

  4. Does the file need to be served outside SPA routing in a special way even if the URL opens correctly?

  5. Is there anything else Zoom checks besides accessibility + exact content?

Would appreciate any guidance from anyone who has dealt with this before.

Thanks!
