Follow these best practices if you're a Facebook Marketing Partner or an advertiser managing ad accounts or Pages. How you handle assets depends on your role and ownership, so here's a list of different approaches you can take.
The 2-tier Business Manager solution is a scalable solution for a Business Manager to create and manage child businesses. It allows you to:
The customer owns the assets and they login to the Marketing Partner app directly. The Marketing Partner app uses the user's token.
The Marketing Partner owns the assets and manages them using employees.
The Marketing Partner manages customer ad accounts by saving or storing customer passwords.
The Customer owns their ad accounts and assets, but Marketing Partner employees need access for customer ad accounts for troubleshooting reasons.
The Marketing Partner owns the ad accounts for customers, while customer owns its own Pages.
The Marketing Partner has multiple ad accounts and customer Pages, and wants to map which assets are for which customer.
The Marketing Partner or customer employees don't want to use their personal Facebook login to access Business Manager.
The Marketing Partner app does not have Ads Management access, but still wants to use the BM system user to invoke Page APIs.
