I want to update a BDM object programmatically.

In my new BonitaSoft project, I use REST API extensions to drive the process. Front-end will be developed later using Ionic and Angular.

Any one know how to do this?

Hi,

The BDM objects have to be updated through a process. With the Bonita platform, you’re building process-based application, which means that the business logic is implemented using processes.

By making sure that each BDM object is updated by a process, you ensure a consistency in your data management, and you get a easy audit trail on your object updates.

Cheers
