What kind of app would I need to build if I want to be able to modify users phone such as directory number and extension and without using Redirect URI?

Previously I was able to do this by creating OAuth app and using redirecting URI to Postman and there I generated the token that I used to make API calls… Is this possible without Redirect URI?

Hi @nbecirovic  
Thanks for reaching out to us.  
It looks like you could benefit from using our Server to Server Oauth app that is an Account level app and does not need user authentication to be able to generate tokens:

> **[Internal apps (Server-to-server)](https://developers.zoom.us/docs/internal-apps/)**
>
> The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform.

Hope this helps!  
Elisa

@elisa.zoom will that still require Redirect?

@nbecirovic  
The Server to Server OAuth does not require a Redirect URL
