The "role" field will always show the "system role", as custom roles are system roles with modified permissions.

If you need to see if the employee belongs to a custom role, you can expand the "roles" field to see the "name" of the role they are in.

GET /v3/merchants/{
                {merchantId}}/employees?expand=roles

Here is an example expanded response of an employee with a custom role named "CustomEmployeeRole":

            "id": "C953DJN87AEDP",
            "name": "Custom Employee",
            "nickname": "Custom",
            "inviteSent": false,
            "pin": "1212",
            "role": "EMPLOYEE",
            "roles": {
                "elements": [
                    {
                        "href": "https://sandbox.dev.clover.com/v3/merchants/T0JBWKG25CF5F89J/roles/CRADD3CKC54UD",
                        "id": "CRADD3CKC54UD",
                        "name": "CustomEmployeeRole",
                        "systemRole": "EMPLOYEE",
                        "merchant": {}
                    }
                ]
            },
