Trying to make a custom booking flow for a course type of booking service.
I’m stuck at the first step. And wanting to load the course sessions so that the customer can view them.
Haven’t found the appropriate code for it.
Example of the upcoming sessions
Hidden absolutely deep within the various sections and the various documentation pages for SDK / REST / Velo and what not, we find the calendar “event” where one can query the schedule id and get the data. https://dev.wix.com/docs/sdk/backend-modules/calendar/events/query-events?apiView=SDK
Glad you found it, and thanks for updating the topic 
Yes. Although the documentation needs a clean up! So messy with all the different areas to peruse.
