If you share access to your Business Center with partners, you can change permissions to control who can access your assets and ad accounts.
Only TikTok Business Center admins can make changes to partner permissions.
To upgrade partner permissions:
Log in to your TikTok Business Center admin account.
Under the Assets section, click Ad Account.
Select the Ad account.
Click on the Partner tab.
Select the partner.
Select permissions from the dropdown menu.
Your partner will now see the shared assets in their TikTok Business Center account until access is removed or changed. To downgrade permissions, you'll have to remove the partner and reassign permissions.
