**Description**  
As mentioned in the below link,  
[https://marketplace.zoom.us/docs/guides/auth/oauth#using-multiple-environments](https://marketplace.zoom.us/docs/guides/auth/oauth#using-multiple-environments)  
I’m trying to use the same OAuth App for multiple env. e.g. [cust1.app.domain.com](http://cust1.app.domain.com), [cust2.app.domain.com](http://cust2.app.domain.com). I have added the callback url as “[any.app.domain.com](http://any.app.domain.com)”.

**Error**  
We I try to redirect to cust2.app.domain, then I get following error:  
`{"status":false,"errorCode":4700,"errorMessage":"Invalid redirect url","result":null}`

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
OAuth

**Which Endpoint/s?**  
[https://zoom.us/oauth/authorize](https://zoom.us/oauth/authorize)

**How To Reproduce (If applicable)**  
Steps to reproduce the behavior:

1. Create an OAuth App
2. Add redirect url as “[http://any.app.domain.com/callbackurl](http://any.app.domain.com/callbackurl)”
3. Now test the Installation URL  
[https://zoom.us/oauth/authorize?client\_id={client\_id}&response\_type=code&redirect\_uri=http%3A%2F%2Fcust1.app.domain.com%3A8080%2Fcallbackurl](https://zoom.us/oauth/authorize?client_id=%7Bclient_id%7D&response_type=code&redirect_uri=http%3A%2F%2Fcust1.app.domain.com%3A8080%2Fcallbackurl)

**Additional context**  
If we add [cust1.app.domain.com](http://cust1.app.domain.com) in allow lists then it works.

I got it working. After reading below post by @tommy

> 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…

The mistake I was making was not including the domain (i.e. [app.domain.com](http://app.domain.com)) in whitelist url.

Thanks! 🙂
