As part of an API upgrade to the Adform data source, users must have the “buyer.advertisers.readonly” permissions included in its authentication to continue to fetch advertiser data.
To support this functionality, we have updated our Adform data source authentication process to include the required permissions.
Update your login
To continue fetching advertisers data for Adform, please reauthenticate the Adform data source by December 31, 2021, according to the instructions for the product you use:
If action is not taken by December 31st, you will start to receive errors asking you to reauthenticate.
Adform will no longer support "direct logins", so you'll need to convert your Adform account by December 31 as well. Learn how to convert your account.
