Hi,
Thank you for reaching out to the Google Ads Scripts Support team.
Upon reviewing your concern, I understand that you are looking to auto build Google Ads Campaigns. I would recommend you to use the bulk upload option available in Google Ads under "Tools>Bulk actions>Uploads". You can refer to
Templates and examples for bulk upload documentation for more information. You can also use the
bulk uploads option available under Google Ads scripts.
Thanks,
Google Ads Script team
