Hi Kara,

thank you for reaching out to us

Unfortunately we don't have hooks (action and filters) at the moment. What we have is a few JS hooks that is triggered depends on the view:

window.beforeAddToCalendarLoaded()
window.beforeBookingLoaded()
window.beforeSearchLoaded()
window.beforeSearchFiltered()
window.afterSearchFiltered()
window.beforeConfirmedBooking()
window.beforeCatalogLoaded()
window.afterSelectCatalogCategory(object_category)
window.beforeCatalogCategoryLoaded(object_category)
window.beforeCatalogServiceLoaded(object_category, object_service)
window.afterSearchActivateService(object_appointment, object_serviceActive)
window.afterSearchGoToSecondStep(object_appointment, object_serviceActive)
window.afterBookingSelectDateAndTime(object_appointment, object_serviceId, object_providerId, object_locationId)
window.afterBookingSelectService(object_appointment, object_serviceId, object_providerId, object_locationId)
window.beforeConfirmBookingLoaded(object_appointment, object_service, object_provider, object_location)
window.afterConfirmBooking(object_appointment, object_service, object_provider, object_location)

JS files are modified (minimized) in public version of plugin (in our development environment is accessible), but unfortunately I can not send you our source code because that is the policy of our company.

All those files that have extension .vue are compressed and minimized in JS files that is very hard and not recommended modifying. So in order to add some other features you can unminify the js and customize it.

We are currently working on customization expansion as well
