API Bookings

Question

Hello,

We are currently putting BOOKINGS into production. We would like to be able to report on customer appointments resulting from booking with the Qliksense application. To allow the application to read the bookings data, we have looked to set up the API. The problem we are having is that the API seems available only in delegated user access and not in application access. This implies a regular authentication of a user.
Is there a solution to allow the recovery of BOOKINGS data by another application?

Thank you
