With the new changes recently made to transition Product Listing Ads to Shopping Campaigns, it is not surprising that AdWords now supports Shopping Campaigns with AdWords scripts.
We are excited to announce support for Shopping campaigns in AdWords scripts. The current release allows you to work with existing shopping campaigns, create and manage product partitions and run shopping reports.
Google has a help guide for using scripts in shopping campaigns here. They have more information on product partitions here in their developers section.
The AdWords team is also asking for feedback on the scripts on their help forums, particularly for bug reports and API improvement suggestions.
