Hi

We are creating a Zoom Oauth app which is set up to support multiple subdomains according to:

> **[OAuth 2.0 - Authorization - Documentation](https://marketplace.zoom.us/docs/guides/auth/oauth#using-multiple-environments)**
>
> OAuth with Zoom
> 
> The Zoom API uses OAuth 2.0 to authenticate and authorize users to make requests. To setup access credentials and request scopes for yo...

([example.com](http://example.com) is used as an… example…;))  
For example, the “Redirect URL for OAauth” is set to http s://any.example.com

Then any of the subdomains \*.example.com can use the app:

The Whitelist URL is setup with http s://example.com.

We also want to use the Event Subscription (webhooks) feature. My question is how do we setup this with multiple subdomains? What should the “Event notification endpoint” point to?  
http s://any.example.com?  
http s://example.com?

Is it even possible to use Event Notifications with multiple subdomains?

Thanks  
Magnus

Hey @magnus,

Good questions, happy to help clarify.

First, regarding the multiple subdomains, please see this post which covers this in a bit more detail:

> Hey @tuancode, @michael.solomon, This is totally possible! slight_smile Let me walk you through how to do this with the base domain of example.com For your whitelist, simply add your base domain: https://example.com Then in your dev/prod redirect url field, add a default redirect, https://any.example.com (this will be programmatically overridden to the correct sub domain, continue reading below) Now, with your install URL ([the url mentioned in Step 1. of the OAuth guide](https://marketplace.zoom.us/docs/guides/auth/oauth#getting-access-token)) in your code, dyna…

As for the webhook endpoint, please note that this will require a designated endpoint/URL for each event. (I believe we connected already over at Developer Support, too, where I’ve provided some more detail).

Let me know if this helps,  
Will
