Announcing v201409 of the AdWords API

Today we're announcing the release of AdWords API v201409. Here are the highlights:
  • Mobile campaigns for search and display. Search Mobile App and Display Mobile App campaign subtypes are now available via CampaignService. These new subtypes are a simplified way of creating campaigns focused on mobile app promotion.
  • Ad Customizers. Ad Customizers previously available for Test Accounts only are now enabled in production. With this feature you can include dynamic values in your ads based on feed data.
  • Currency support for conversions. Conversion trackers (including offline conversions) now support currency specification. You can also set default currency per tracker.
  • Website call conversion tracker. This tracker allows the collection of conversion stats for calls made on a script-generated phone number placed on your website.
  • Rule-based remarketing lists. The new API version allows you to create and manage rule-based remarketing lists. This feature allows you to use simple rules to better target the people who visited your website.
  • Better Labels handling. LabelIds column is now available in all relevant reports. We've also added both Labels and LabelIds columns to the Criteria Performance report.
  • Updates to reporting. A new Extension Placeholder report is now available for retrieving consistent extension stats. Reporting interface was extended to allow you to control the presence of report headers and footers in the response.
There's also an important API-level change in v201409. Starting this version, the clientCustomerId header is now a required header for calls to all services except CustomerService. If your application relies on a default account identified by authorization credentials, you need to update it to send a valid customer ID for every request. You can obtain the customer ID via a get call to the CustomerService.

If you're still using v201402 of the AdWords API, please note that it's being sunset on November 6th, 2014. We encourage you to skip v201406 and migrate straight to v201409. If you're using v201406, be aware it's now marked deprecated and will be sunset on April 6th, 2015.

As with every new version of the AdWords API, we encourage you to carefully review all changes in the release notes and the v201409 migration guide. The updated client libraries and code examples will be published shortly. With this release, we've also updated the Required Minimum Functionality document to include some of the newly added features that are now required in third-party tools. If you have any questions or need help with migration, please post on the forum or the Ads Developers Plus Page.
