It's easy to write code using the AdWords API in the programming language of your choice, thanks to all of our client libraries. But when it comes to written language, you're more constrained--our recent developer documentation has only been maintained in English.

We're happy to announce that this is no longer the case, and our Developer's Guide now features a Chinese and Japanese translation. If you're not automatically redirected to the appropriate language when you visit that page, use the popup menu in the upper right hand corner of the web page to switch to one of the supported languages.

Please note that only the v12 version of the Developer's Guide has been translated. We're working hard to get v13 translated as well, and hope that the v12 documentation proves useful for v13 developers--the majority of the documentation is the same between the two versions. We will be leaving the v12 documentation up on the site for an extended period of time.

We'll be releasing translations for additional languages in the future, so stay tuned for more updates!

We'll be performing routine system maintenance on Saturday, February 21 from approximately 10:00am to 2:00pm PST. You won't be able to access AdWords or the API during this time frame, but your ads will continue to run as normal.

Cheers,

In accordance with our policy of sunsetting older versions of the AdWords API, we will turn off access to version 12 of the API on Monday, February 23, 2009. Version 13 of the API has been available for over four months now, and supports a number of new features. We hope that you've already taken the opportunity to upgrade your code.

The latest versions of the publicly available official Google client libraries all support version 13 of the API, so if you're using one of those, please check the relevant README file for information on how to switch from version 12 to 13.

As always, if you have any questions about the AdWords API or upgrading to our latest versions, you can check out our Frequently Asked Questions or ask them in our developer forum.
