What was our customer's goal?

Our customer's requirement was that their booking system be able to utilize pricing plans to allow members to book a specified number of sessions in the studio per month, but only for a certain amount of time per day.


How did we solve their problem?

Wix Bookings & Wix Pricing Plans allowed us to easily enable members to book a specified number of sessions per month, but limiting the duration of the sessions per day was trickier.


Fortunately, using the built-in Velo Booking Events backend system and Velo's Wix Pricing Plans Backend API, we were able to implement these limitations.


What is the Wix Bookings app?

How did we use Velo?

First, as with all Velo Events, we had to create an 'events.js' file in the Backend section of the Code Files tab in the Wix Editor.


The next step was to hook into the Wix Bookings app Booking Confirmed event, as documented in https://www.wix.com/velo/reference/wix-bookings-backend/events/onbookingconfirmed, so that when a booking was confirmed, our system would check to see if it was booked with a Pricing Plan. If so, use the Wix Pricing Plan Backend API to get the plan details and then pull the daily limit for that Plan which was stored as a Pricing Plan perk.


Then, we used the Wix Bookings Backend to query for bookings that were made by the same member for the same day that had also been booked with their pricing plan. Once these bookings had been queried and filtered, their durations were added together to see if their daily limit had been met. If so, we then used Wix Bookings Backend API to cancel the booking and notify the customer that the booking they had attempted to book exceeded their daily limitation.


What was our customer's reaction to the solution?
