We have added the following new features in AdWords scripts.

Ad customizers
AdWords scripts now support ad customizers, a more advanced version of ad params. Ad customizers adapt your text ads to the full context of a search or the webpage someone's viewing, by inserting a customized parameter within the ad. Ad customizers let you customize your ads for each query without having to create a separate ad for each variation.

AdWords scripts allow you to create ad customizer sources, add or update items in the sources, and create parameterized ads. You can also target an ad customizer item to a specific campaign, ad group or keyword, and track the performance of ad customizers using the PLACEHOLDER_FEED_ITEM_REPORT.

To learn more about ad customizers, refer to our code snippets and guide. Also, check out the brand new ad customizers solution that shows how to use this new feature in your account.

v201409 reports
We now support AdWords API v201409 reports in AdWords scripts. See blog post for more details.

Product ads
You can now retrieve your product ads using the ads() method of the ShoppingAdGroup. You can create new product ads using the newAdBuilder() method of ShoppingAdGroup.

We hope you enjoy these new features. If you have any questions about these features or AdWords scripts in general, you can post them on the developer forum.

Today, we are introducing ad customizers, a new way to insert dynamic information into your ads. Ad customizers work similarly to ad parameters. They allow you to set up a feed with dynamic data, targeted at specific campaigns, ad groups or keywords. Your ads then reference the information in those feeds so that the values are inserted when the ad is served. You can also create ads that dynamically count down to an event, by inserting {=COUNTDOWN(...)} in your ad. Learn more about this new feature here.

Ad customizers are currently supported in AdWords API test accounts. Production accounts need to be whitelisted before you can use this feature. You can sign up for this feature here. Once your account is whitelisted, you will receive a confirmation email and can start using ad customizers in the whitelisted account. We whitelist accounts in batches, so expect some delay between signing up for the feature and getting your account whitelisted.

If you have any questions about this feature or the AdWords API in general, you can post them on our developer forum. You can also follow our Google+ page for updates about the AdWords API.
