Change statuses of users in our DB from CRM

Change statuses of users in our DB from CRM

Hi all,

Hope you are well(:

I was wondering rather I can control statuses of users in my native system (not the CRM) using Zoho CRM.

For example: a user in my system has a status of "Authorized" to conduct actions in my web app - let's say that the user is authorized to trade up to an amount of $1000 within my system - now I want to change his/her status from "Authorized" to "Unauthorized" in the CRM and that it will affect the actual status in the system.

1. Is it possible? (I haven't seen such option going over the API documentation)
2. If it is possible I would love to get a reference to where I can read more about it.

Thanks in advance, you are great(:
Yoni
