Using API Rest

Hi,
I'm using an API to bring the information to the person who is logged into the portal, the information that brings me the API such as the name or department to which it belongs within the organization could be stored in a variable using the UI Designer, this can be?
I apologize if I'm not being very clear with the question, I do not have much experience using BonitaSoft.

Regards,

Victor

PD. I'm using subscription Edition
