Can anyone help with an integration with Zcal.co for a complete beginner?

What are you trying to achieve?

Trying to do a VAPI integration voice bot to web calendar appointment. I have Vapi all setup (thanks you tube!) but I see alot of other calendar setup tutorials, but none for Zcal.co . I am certain that I can use webhooks to do this, but I don’t know enough to actually do so… so can anyone help me with this or should I just settle on an alternative calendar? Thanks for your help either way!

Steps taken so far

I have a VAPI webshook pulling the calendar appointment times @ dates but I don’t know how to create a webhook for zcal.co to input the data I have captured.
