Your customers remain in your app on website when they place their event or appointment booking via JRNI.
This is the most common use case with the JRNI platform and APIs.
JRNI offers real time booking notification webhooks so you can design, manage and control your customer communications.
See https://dev.jrni.com/docs/drops-reference-guide on how your webhook payload can be customised to your needs using Liquid
The JRNI Bulk Import API allows you to create users (Administrators), bookable staff to take customer appointments and their associated work schedules as well as add and remove locations where customers can attend appointments.
