Setting up iClicker for Online Classes is part 1 (length: 15:45) of the Polling for Online Classes webinar:

Polling for your online classes using iClicker. This webinar is for instructors already using iClicker in their class who want to continue to use iClicker in live online sessions. Your iClicker questions can be presented in your live Zoom sessions. Students can respond using their smartphones, laptop computers, and tablets from their location anywhere in the world. This webinar will show you how to set up your iClicker program to enable the student app use if you are not already allowing this feature. Also, we will share a form with you to request free account information for any student who currently uses a clicker in your class so they can use the iClicker Reef Polling app at no charge.
