Hi. I need to create a meeting on behalf of any zoom user. It seems that an OAuth application should be used, but I did not find how to authorize server.  
Steps:

1. zoom user adds my app
2. server creates meetings for the user(how to do this if a token is needed to send a request?)  
Store the user’s refresh token in the database?  
Is there a way to authenticate on the server side?

Hi,

In order to make API calls on behalf of the user, here are the steps:  
1] Create an app in the marketplace. Fill the necessary information and get the publishable URL.  
2] The user will click on the publishable URL which will take them through the authorization flow  
3] Once the user approves the app, you will get a code (from the redirect URL)  
4] Use that code to generate an access token / refresh token  
5] Use the access token to make api calls  
6] Use the refresh token to get a new access token when current one expires.
