Is possible that I can use below zoom authentication endpoint:

%[https://zoom.us/oauth/authorize%](https://zoom.us/oauth/authorize%25)

, from a console application in C# where there is not user pages or user interaction with the app, to be more specific I’m building an integration between dynamics 365 and Zoom API to create a link meeting. So I don’t know is possible create a OAuth Zoom App for my goal. When I create a Server to Server OAuth zoom App don’t have any problem.

Using this endpoint: %[https://zoom.us/oauth/authorize%](https://zoom.us/oauth/authorize%25) , returns a html response where the user needs enter username/password to get an Token and then create the meeting, but I can’t handle from my backend code the Html returns by oauth/authorize

Thanks for you help

Hi Elisa, I haven’t found a solution for the issue yet. I’m not sure if that kind of Authentication is compatible to use it from a C# project library

Hi @vladimir.rivera  
Sorry to hear that!  
Unfortunately to implement OAuth, it requires user authorization and there is no way to bypass it.  
Is your app supposed to be for internal use? or do you mean to have your app used by 3rd party users?
