About Zoom Live Class
The Zoom Live Class module utilises the https://marketplace.zoom.us/ meetings service to create live classes for students and live meetings for staff members. In this module, teachers or authorised persons can create live classes for students based on the timetable period, and further, students can join these classes from the student panel. Any authorised staff can create staff meetings, and the staff concerned can join these meetings. To use this module, users must have the Zoom app installed on their devices. In Smart School, the Zoom Live Class module only creates classes and meetings using the Zoom API, and users can start or join these classes or meetings. All processing and management are done by https://marketplace.zoom.us/ If you are using a Zoom paid account (like a 10 host license), then you should create individual host user Zoom API credentials and add them to Smart School's Zoom Live Class in the 'Add Credential' option present in the teacher account. Since Zoom doesn't provide the ability to start multiple Live Classes simultaneously for a single host, even if you are using a Zoom paid account, you should create multiple host accounts in Zoom to run multiple simultaneous Live Classes, each started by a separate host.
Zoom Live Class Module Workflow: First, we will add Zoom account API credentials on the settings page and set the Zoom API. Next, we will create a Zoom Live Class or meeting, and then we can start the live class or meeting. Students can join the live class, and staff members can join the meeting. Furthermore, we can check the join report for the live class or meeting.
Note: Zoom Live Class is a Smart School add-on, so to use it you should purchase it separately and install it in your Smart School.
How to configure Zoom Live Class?
Before creating a Zoom Live Class or Live Meeting, you must have a Zoom account and Zoom API credentials. If you don’t have a Zoom account or API credentials, check this https://www.youtube.com/watch?v=voJOIavlKTk video tutorial.
To configure Zoom Live Class, go to Zoom Live Classes > Settings; here, enter the Zoom API Key , Zoom API Secret details and check Teacher API Credential and Zoom Client App Enable/Disable and then click on Save button. The API credentials entered here are known as the Global API Key in Smart School, so we recommend using Zoom paid plan API credentials; on the free plan, you can run only a single class or meeting at a time.
If you disable Teacher API Credential option, teachers will have to use the global API key and will not be able to create their own API credentials. If you enable the Teacher API Credential option, teachers can add their own API credentials from their teacher account by clicking on the Add Credential button, to create Live Classes using their own API key.
If you enable Zoom Client App option, users will have to install the Zoom Client App on their machines. If you disable the Zoom Client App option, users do not have to install anything; classes and meetings will start on Zoom Web SDK. Zoom Web SDK is not as mature as the Zoom Client App, so some features may not work properly or may be missing in Zoom Web SDK. It is therefore highly recommended to use the Zoom Client App to avoid Zoom Web SDK issues and use full-featured Zoom services.
Note -
- If you are using Zoom Web SDK (Zoom Client App disabled), your Smart School must be running on SSL (https); otherwise, you will get error messages and Zoom classes or meetings will not start.
- If you are getting "Invalid access token" error message while creating a Zoom Live Class or Meeting, it means you are using incorrect API credentials for your Zoom account, so check the API credentials you have entered.
