REST API for filtering employees based on city

[jp_CR7]

I have an employee table that contains information about various employees in the company along with their respective branches. A branch manager should only have access to the employees of their specific branch. For instance, if someone is the manager of a particular branch, they should only be able to view the employees associated with that branch. To facilitate this, I have developed a REST API job with SAML authentication, where the users are the branch managers stored in Apache Syncope. How can I implement this in Syncope and design the job in Talend Studio?
