Hi Giorgos,
Thank you for reaching out to the Google Ads Scripts Forum Channel. Please excuse us for only getting back now as your message failed to be routed to our support queue.
I'm afraid that
App campaigns are not yet supported via Google Ads Scripts. There already is a request filed for this to be exposed via Google Ads Scripts, however, please do note that our team would be unable to provide a definite timeline with regard to it's release and would instead recommend you keep an eye on our
Ads Developer Blog <
https://ads-developers.googleblog.com/search/label/google_ads_scripts> for future updates and latest announcements.
Let us know if we can assist you with anything else.
Best regards,
Google Ads Scripts Team
