How Can I get zoho users id on deluge

Hi, 

I'm trying to build connection from creator to zoho projects and I want to assign user once I create new Task in deluge.

and Its work fine if I assign my zoho id user to : "person_responsible".

Is there any way That I can get all the users ids on the and assign them in person_responsible in deluge without assign the id manually?
