To enable Bookly CRED (Create, Update and Delete) Rest Api operations please see the plugin.
We created the “Bookly Read Rest Api” addon to allow users to read appointments, staff, services and customers data created with the Bookly plugin from anywhere. In it’s most basic form, a rest api separates the content from its presentation, freeing developers and users to use their data as they would like. The rest api is provided in a simple to use and understand json format.
