Minimum security needed to use REST Service Employees

Summary

We would like to setup a user with just the needed privilegies

Content

Hello,

We are trying to updated the worker email for employees using webservice functionality. We are doing that but providing so much security for the user in charge of doing this update action. In fact, we have tow different populations from different countries on HCM and the current user is able to update information for both of them, when the targetted population is one of these countries.

Does anyone face the same requirement? Any approach would be highly appreciated. 

Thanks in advance.

Best regards.
