Note this change affects Advertiser accounts only. MCC accounts can have only one manager as before.
Changes for the API users
There are a few API changes introduced by this new feature:
- All new Account links are now of the UI_AND_API type. Existing API_ONLY links were not updated and are still valid as defined.
- Every managing account with an API token will now receive 100% of free units (if eligible) for each linked client account based on its monthly spend. Previously, UI_AND_API type of links provided only 10% of free units quota.
