As many of you are well aware, the 
DFP API Playground is a great tool to explore the 
DFP API. With it, you can easily test PQL statements and examine the JSON equivalent of the objects you fetch. Best of all, it acts as a full reference implementation of how you should integrate the API with App Engine, touching on features such as OAuth2 authentication, task queues, and channels. 
Now, we are announcing the new 
GitHub project for the DFP API Playground, featuring all the benefits of being hosted on GitHub, improved getting started instructions, and revamped project downloads.
Taking it for a spin
The first thing you’ll notice when visiting the project is that we’ve made it incredibly easy to 
get up and running.
With Maven 
If you are a Maven user, it’s as simple as modifying the 
appengine-web.xml file and running
 
 mvn appengine:devserver
We’ve also included an 
m2e project so developing with Eclipse is easier than ever. Just import the extracted dfp-playground-maven-project download into Eclipse, modify the appengine-web.xml file (in the src/main/webapp/WEB-INF directory), and run the DevAppServer.launch profile in the eclipse-launch-profiles folder.
With Google Plugin for Eclipse 
We also heard you loud and clear that not everyone uses Maven, so we’ve added a 
Google Plugin for Eclipse project 
download which includes all jar dependencies. As with the Maven project, just extract the dfp-playground-jars-and-google-eclipse-plugin-project download, import it into Eclipse, 
add Google App Engine functionality to the project, modify the appengine-web.xml file (in the war/WEB-INF directory), and run the project like any other App Engine project.
If you’d like to learn more, take a look at the 
README. As always, we are open to any feedback, so please don’t hesitate to leave us any feature requests in the 
issues section. Also, if you’d like to contribute to the project, we welcome any patches (just make sure you become an 
official contributor first).
In the coming months, we’ll be adding even more functionality to the application, so stay tuned and happy hacking!
