Hi,
Thank you for reaching out to the Google Ads API support team.
Kindly note that updating or creating tracking templates, final URL suffixes, and custom parameters for asset groups is not currently supported by the
Google Ads API. I'll raise a request to add this feature to become available in the Google Ads API. However, I cannot provide a scheduled timeline for the availability of this feature. So, I would recommend you to follow our
Release Notes and
Blog Post for further updates.
