Hi Harrty!

We have API Routes for Amelia, but most of them are protected and depend on the permissions that are set in WordPress Accounts. 

You can find all API Routes in this file ../wp-content/plugins/ameliabooking/src/Infrastructure/Routes/Routes.php

At the moment we have some JavaScript hooks that trigger after confirm booking, before confirming booking, etc; which are triggered depending 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.

Hope this helps!
