Hi Lan,
Thank you for reaching out to us.
Kindly note that new accounts will only be able to create image and location assets and not extensions. New accounts will be treated as accounts that have been migrated. With this, if your account has been migrated or is new and you attempt to create an extension the mutate request will be rejected and you will receive the error: LEGACY_EXTENSION_TYPE_READ_ONLY. You may check this blog post (https://ads-developers.googleblog.com/2023/07/image-and-location-assets-in-new.html) for more information.
To verify your account, you may use the following fields from v13 or greater in the Customer resource to track the status of your account:
On the other hand, you may also check this documentation (https://developers.google.com/google-ads/api/docs/extensions/assets/asset-extensions) for more information on asset-based extensions. You may see there the current extensions that support assets, with more being added later.
