Zoom SDK instant meetings with users in account

I want to integrate a Zoom SDK integrated app and host instant meetings like in any other chat apps between the users of my app.
How can I create users. I saw the create user api. the users thus created how can I initiate a call between two such users. I need them as users of my iOS app, not zoom users. And record their chat and call history.
How can I implement this.

Hi Liza,

You may use SSO login: https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/start-join-meeting/sso-login-user/authentication

Or you may use API authentication(use zoom token and zoom access token) to start/join meeting:https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/start-join-meeting/api-user/authentication

Our demo app has both implementation, you may have a try and find out which one fits your use case.

Hope this helps. Thanks!
