Hi,
Thank you for reaching out. I believe
this example is similar to the one you shared from the AdWords API. Also,
here is an example from the Google Ads API documentation for for creating and updating feeds. You can also take a look at the
Services migration guide for how to map services from AdWords API to Google Ads API. This should be helpful for reproducing the code.
Regards,
