Citat:
he AdWords API Sandbox is an environment that replicates the API of the live site, for developing, testing and debugging applications that use the AdWords API. When a developer logs in, AdWords accounts are automatically created in the Sandbox, then the developer can create and run campaigns, adgroups, creatives, and other operations on those accounts without incurring any quota. There is no quota on the Sandbox system -- users are free to make all the calls they want. All account, campaign, adgroup, creative and criteria data that you submit can be read back as usual. However, the extra information based on usage and ad impressions such as traffic estimates, statistics, reports, and keyword suggestions, will be fake. The details on fake data are listed throughout this document. The Sandbox is not meant for load testing.
Developers can use this Sandbox to:
* Develop programs without expending their quota
* Test code that modifies mock AdWords campaigns without affecting live campaigns
* Develop against new or changed AdWords API methods before the changes go live on the real service
* Create client libraries without requiring a real AdWords account (and thus a credit card)
