Is it possible to fetch data from a REST endpoint and save some of its fields in a Business Object?

Summary:

Integration between a Visual Builder/VB Web Application and HCM REST endpoint.

Content (required):

We already have the employee/worker data in Oracle HCM and we are building a Web application using VB or VBS.

We can call a Worker REST API to get some data (First name, last name, etc.) then we would like to add more fields/attributes to the employee business object.

How can we save a copy of the data from HCM in the employee business object?

How can we synchronize the data regularly afterwards?
