Creating and Sending a Calendar Event for Each Event in a List

I am using the Full Calendar Plugin and have set it up so that my users can select multiple events in that calendar. Each event goes into a shopping cart then they can checkout.
What I want is for a separate calendar event (invite) be sent to the user for each event in the cart that is purchased. In the calendar invite I’d like there to be a Zoom link and perhaps even a Google Meet and/or other webconferencing app links.
I read through several threads on the forum suggesting Zapier and have tried to set that up but in the Bubble workflow it asks for the Webhook and I still don’t know what to put there.
Also, in Zapier it asks for the Zap ID but doesn’t specify where to find that.
I’ve included several screenshots and appreciate any help.
Thank you in advance.
