Start a Meeting - Non-login user

You need to obtain the User Token and Zoom Access Token (ZAK) in order to start meetings for a user. They are unique authentication tokens required to host a meeting on behalf of another user.

Example of getting User Token and ZAK here

More info about the User Token and Zoom Access Token here.

In order to run the example app:

1. Create an JWT app to get a JWT token using the instructions here.

2. Create a meeting (with a host of course) then get the Meeting ID (can be a 10 or 11-digit number).

3. Use the Zoom API to obtain the tokens from the host.

   # User token
   curl --location --request GET 'https://api.zoom.us/v2/users/<zoom_user_id>/token?type=token&access_token=<jwt_token>'
      
   # Access token
   curl --location --request GET 'https://api.zoom.us/v2/users/<zoom_user_id>/token?type=zak&access_token=<jwt_token>'
   

   Note for obtaining tokens:

   The user must log in using their email and password to get the user token. If a user signed into Zoom using Google or Facebook, a null value will be returned for the token.

4. Pass the meeting ID and tokens to the plugin.
