How can you effectively utilize Yahoo! Japan Business Manager to grant a third-party agency access to specific ad accounts without providing full administrative control?

Yahoo! Japan Business Manager allows granting third-party agencies access to specific ad accounts with controlled permissions, avoiding full administrative control. The process involves adding the agency's Yahoo! Japan ID to the Business Manager and assigning them a specific role for each ad account. First, the agency must provide their Yahoo! Japan ID associated with their Business Manager account. Within your Yahoo! Japan Business Manager, navigate to the 'Users' section. Add the agency's Yahoo! Japan ID as a new user. Then, for each specific ad account you want the agency to manage, grant them access individually. When granting access, select the appropriate role for the agency. Instead of 'Administrator', which provides full control, choose a more limited role like 'Standard User'. The Standard User role allows the agency to manage campaigns, create ads, and generate reports, but restricts access to sensitive settings like billing information or user management. You can also create custom roles with specific permissions to even further limit what the agency can do. By assigning a Standard User role (or custom role with limited permissions) at the ad account level, the agency gains the necessary access to manage campaigns effectively, while the sensitive settings remain protected within the control of the account owner. This method gives granular access control to ensure security.
