We are attempting to retrieve call extensions in a customer account through the Ads API. The customer has shown us the call extensions through the UI.
However, the following query to the customer's account returns a list of assets with type IMAGE and TEXT only. None of the entries show the phone number or country code fields:
SELECT asset.call_asset.country_code, asset.call_asset.phone_number, asset.id, asset.name, asset.type FROM asset
The documentation claims that all call extensions have been auto-migrated to the asset format as of Feb 15. Therefore, there is no documentation on how to retrieve the call extensions of the legacy format.
Could it be that the call extensions are in the legacy format and thus cannot be retrieved under Assets? If so, how can the call extensions be retrieved nevertheless? This is a major issue for the continuity of our services.
Thank you.
