Hello Zoom Marketplace team,

I’m preparing **Midlyr** , an **admin-managed General OAuth app** , for Marketplace review. Midlyr uses read-only access to customer-authorized meeting recordings and transcripts for compliance review.

Our company domain, **[midlyr.com](http://midlyr.com)**, is already verified through a DNS TXT record. The remaining domain check is **nango.dev** , because our OAuth redirect URL is:

`https://api.nango.dev/oauth/callback`

We use **Nango as our third-party OAuth provider** to handle authorization callbacks, token storage, and refresh. Nango owns this domain, so we cannot add DNS records, HTML files, or meta tags to it.

Could a Marketplace specialist help us complete manual validation or approval of this Nango-hosted callback domain? I can provide our Marketplace app ID and any supporting details by private message.

Nango’s Zoom setup guide: [Set up Zoom with Nango - Nango Docs](https://nango.dev/docs/api-integrations/zoom/how-to-register-your-own-zoom-api-oauth-app)

Thank you.
