Hi @elisa.zoom, I’m building a Zoom app that integrates with n8n (workflow automation platform) and need help with domain validation for marketplace submission. App Details: - App Type: OAuth app - Use Case: Internal use only - Purpose: Automate Zoom workflows (meeting creation, recording management, etc.) via n8n for internal and clients Domain Validation Questions: 1. n8n Hosting: - n8n Cloud instance: halfdozen.app.n8n.cloud 2. Domains to Validate: - Main app domain: [workway.co](http://workway.co) - n8n instance: halfdozen.app.n8n.cloud 3. Specific Issues: - Do I need to validate both [workway.co](http://workway.co) and the n8n cloud domain? - Should I use Server-to-Server OAuth instead since n8n handles the backend automation without end-user UI? - How do I handle validation when the app runs entirely through n8n workflows? Any guidance would be appreciated! ---

Hi @mjhalfdozen, if you’re submitting to the Marketplace you must [verify any domains your app uses](https://developers.zoom.us/docs/build-flow/verify-domains/) (redirect URLs, webhook bases, policy pages) and it’s a one-time, account-level check You can’t validate `n8n.cloud` since you don’t control it, so validate `workway.co` and route the OAuth redirect through it (e.g., `/zoom/callback`) then relay to n8n If your automation only acts on your own Zoom account without user interaction, prefer [Server-to-Server OAuth](https://developers.zoom.us/docs/internal-apps/s2s-oauth/) - Zoom’s guidance on [when to use S2S vs OAuth](https://devforum.zoom.us/t/when-to-use-server-to-server-oauth-app-and-when-to-use-oauth-app/75274) fits this If clients in other Zoom accounts must authorize, use a standard OAuth app and Marketplace distribution; build your flow around a redirect hosted on your verified domain per [Create an OAuth app](https://developers.zoom.us/docs/integrations/create/) For n8n-only execution, keep the Zoom OAuth redirect and webhooks on your verified domain then hand off to n8n via HTTP nodes - the key is that Zoom sees only your [verified domains](https://devforum.zoom.us/t/domain-validation-explanation/87699) The solution here really depends on your use case so hopefully the info above helps inform you on which solution to use ---
