Third Party App Connectivity

Third Party App Connectivity

Hallo


i am new to zoho crm and i am interesting to "connect" it to another app that i have.What i really want to do is to bring a field value (custom field )  that i added to the users tab ,and get the value of it for each user.In other words i want to get the value inside a custom function of a custom field that i created in a user tab.Is this possible?
