Google Launches A New Backend For Bulk Uploads In Google Ads Scripts

just launched a new backend for bulk uploads in Google Ads Scripts. Starting today, you can opt into the new experience by specifying the useLegacyUploads flag when creating a new bulk upload:

var upload = AdsApp.bulkUploads().newCsvUpload(columns,
    {useLegacyUploads: false});

For now, if you don’t specify a value, the default will be true, which will result in no change of behavior from before this feature. Starting on July 12, 2021 we will change the default to false, but you can still opt out for a time by explicitly passing useLegacyUploads as true. On February 1, 2022, we will disable the use of legacy uploads altogether.
