Hi Nick,
Thank you for reaching out.
It appears that you have also reached out to us on a separate thread regarding this same concern. In the event that you were not able to receive our response, then allow me to respond to you here instead.
Automated extensions are created automatically in the Google Ads UI, that being said, you may only be able to manage these extensions in the UI. For the list of supported extensions in the API, you may refer
here.
I hope this helps.
Best regards,
