Starting with Marketing API V8, you no longer need the
ads_management permission to access product catalog endpoints. Moving forward, you will need the
catalog_management permission to call those endpoints. Developers who have had access to catalog endpoints via
ads_management in the last 90 days will be automatically migrated to
catalog_management permissions by August 14, 2020.
From now until January 31, 2021, developers are still able to call product catalog endpoints with the
ads_management permission. After the January deadline, the
catalog_management permission will no longer be associated with ads_management, so users will have to explicitly grant
catalog_management permission for your app.
To be update your catalog your submission must include business_management or your app must have been approved for business_management in a previous submission.
