Integration of Contacts

Integration of Contacts

Hello - 

I am creating an application with ZC.

In many forms/tables, I need to access basic information about Individuals and/or Companies ie, name, address, birthdate, etc)

Information that could happily live in Zoho Business: Contacts

Is there a way for my AC application fields to lookup the data from Contacts? 

Or, do I need to create it from scratch within my application?

Thank you -
Marion
