how to connect booking analytics of wix dashboard to repeater app?

Hello,

I am afraid it’s not possible to get the information from the Dashboard. Using Dev Mode, you can get the information from the following Wix Bookings collections:

Corvid: Wix Bookings “Services” Collection Fields
Corvid: Wix Bookings “Schedule” Collection Fields
Corvid: Wix Bookings “Staff” Collection Fields

And then populate this information to a Repeater:
About Displaying Database Content in a Repeater

If you have any further questions regarding Analytics for Wix Bookings , you would be better suited going through Wix Customer Care as they know best.
