Hi bmemmen,
As mentioned above, that part needs to be handled by the developer. One possible solution might be: Once the host invites someone, collect the meeting info from SDK, send it your backend or to the invited user; On the invited user’s site, have a listener that listens to the invitation, once received the meeting info, show it to the user and ring the call.
Please note that the above steps would just provide a similar user experience as you are inviting others on the Zoom client. It won’t allow you to invite your Zoom contact directly like the Zoom client since our SDK does not have the access to your contact list.
Hope this help. Thanks!
