Hello Zoom Marketplace team,

Our app, delightfulOS, uses Nylas Hosted OAuth to connect users’ Zoom accounts.

We need manual domain validation for [nylas.com](http://nylas.com) because this domain belongs to Nylas. We cannot modify its DNS, upload an HTML verification file, or add a meta tag.

App type: General, user managed  
Production Client ID: RWCV8i3SPC5dhUwKuabmw  
OAuth redirect URI: [https://api.us.nylas.com/v3/connect/callback](https://api.us.nylas.com/v3/connect/callback)

Nylas setup documentation:

> **[Authenticating Zoom Meetings accounts with Nylas | Docs](https://developer.nylas.com/docs/provider-guides/zoom-meetings/)**
>
> Connect Zoom accounts to Nylas, and automatically create conferencing details for meetings.

Please advise on the steps required to approve this callback domain for our app.

Thank you.
