Implicit Permission
When a user is assigned a role (for example, Organization Administrator or Device Enrollment Manager) at an organizational unit, they can sign in to the Apple Business web portal and view users and user groups for that organizational unit. This read access is implicit—it comes automatically with any role assignment except the role of Staff. The user doesn’t need a separate “read users” permission because the ability to view the information is bundled into the role itself.
Apple Business API accounts work the same way. When an Apple Business API account is assigned a role, it implicitly gains read access to users and user groups just like a web portal user would. The only difference is scope. The Apple Business API accounts are assigned at the root organization level, so their implicit read access extends to the entire organization rather than a specific organizational unit.
Note: If your organization created Apple Business API accounts in Apple Business Manager prior to signing into Apple Business for the first time, those accounts can’t sign in to the Apple Business web portal.
