Most of you have probably heard about Google App Engine, which lets you write web applications that run on Google's infrastructure. But did you know that the code which you develop using the AdWords API can be easily hosted on App Engine, thus making it many times easier to build, maintain, and scale your application as your traffic grows?
Today, we'd like to release a demo application that can be hosted on App Engine and is uses the AdWords API to communicate with the Sandbox environment (it is just as easy to access production AdWords accounts). In this demo, we access a given Sandbox account using the AdWords API and illustrate the following operations and features:
- Retrieve existing campaigns.
- Retrieve stats for each campaign.
- Add new campaigns.
- Update a campaign's budget.
- Retrieve existing ad groups.
- Add new ad groups.
- Keep track of API usage for each user in a datastore.
We hope this demo will start you off in creating innovative and cool applications that take advantage of the AdWords API's ease of use and Google's infrastructure.

We'll be performing routine system maintenance on Saturday, May 16 from approximately 10:00am to 2:00pm PDT. You won't be able to access AdWords or the API during this time frame, but your ads will continue to run as normal.

We want to take a minute to notify all AdWords API developers about an upcoming change in the way bids are handled in campaigns that make use of the Budget Optimizer. If none of your campaigns use the Budget Optimizer, or if you never plan on turning the Budget Optimizer off, then feel free to stop reading (and get back to trying out the new v2009 Sandbox!).
Each Campaign object has a budgetOptimizerSettings property, which in turn has a takeOnOptimizedBids setting. Currently, if takeOnOptimizedBids is set to false and you turn off the Budget Optimizer in a campaign, the original bids that were manually set for the ad groups and criteria contained in the campaign will be restored. In other words, the AdWords API will save your old bids from before the Budget Optimizer was turned on, and restore them when it is turned off. If takeOnOptimizedBids is set to true, however, the old bids will not be restored when the Budget Optimizer is turned off. Instead, the last bids that were automatically set by the Budget Optimizer will persist for the ad groups and criteria in your campaign.
You can, if you wish, use the AdWords API to manually update the bids for ad groups and criteria once the Budget Optimizer is turned off in either scenario.
The upcoming change will effectively treat takeOnOptimizedBids as if it were set to true (regardless of what it is actually set to) for all campaigns using the Budget Optimizer. Once the Budget Optimizer is turned off, all bids will be set to the last bid used by the Budget Optimizer. This change will match the behavior currently in place when the Budget Optimizer is turned off via the AdWords web interface.
We're planning on making this change to AdWords API behavior on May 19. It is not likely that you will have to make any substantial changes to your code in advance of this change, but please take the new behavior into account when you write code that turns the Budget Optimizer off.
