How to use the booking api from external service

Hi folks,

i’m currently working with a client that provides bookings on his wix site. I offer a marketplace for tickets. We both agree that it would be nice for my client to place his bookings on my marketplace.

I saw here that there is a nice API https://www.wix.com/corvid/reference/wix-bookings.html .
As my client is not the most technical guy on earth, I’m a bit stuck with some questions. Maybe someone here is able to point me into the right direction:

To receive a set of bookings available I should do a query as described here:

A query on the Bookings/Services collection.

  1. How to do this from an external service?

  2. What Auth is needed?

  3. Which endpoints needs to be called and how to integrate those ?

  4. How to import wixData from’wix-data’ as an external service?

Thanks community, have a nice day.
