Version 1.3 of the AdSense Management API is now available and comes with new features to help you retrieve more publisher and reporting information.

Metadata for reporting dimensions and metrics
This is a highly requested feature that provides information on the list of available dimensions and metrics for the publishers, as well as their compatibility. This is useful to help developers avoid generating reports with invalid dimensions and metrics.

You can now list the publisher’s current alerts, in their default language or in the one you specify.

Ad code
You can now programmatically fetch the code of an ad unit using getAdCode.

Remember to visit the AdSense API forums or our Google+ page if you need any help implementing these new features!
