In AdWords API v201406, we introduced a smarter way for you to manage URLs in AdWords. You can now designate which part of your URL specifies the landing page, and which part is used for tracking.

Upgraded URLs were previously supported only in test accounts. Today, we are making this feature available in production accounts on a whitelist basis. You can sign up for this feature here. Once your account is whitelisted, you will receive a confirmation email. You can then start using upgraded URLs in the whitelisted accounts.

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.
