Using GData Services

Google provides access to user-specific data stored in Google services, like Calendar events and GMail Contacts, with the Google Data (GData) family of APIs. The GData APIs enable reading and writing Google data via a simple standard protocol. Using modules developed by the GData team, App Engine developers can retrieve, write, update and delete data stored in other Google Services.

To add the ability for your application to access Google services:

1. Download the GData Python Module.
2. Configure the module to work with App Engine.
3. Use the GData API to request permission from the user to access their data.
4. Access the service.

For a detailed tutorial on using GData APIs in your App Engine applications, see the article Retrieving Authenticated Google Data Feeds with Google App Engine in the Articles section of this documentation.

The Google Data APIs Python module includes support for the following Google services:

• Authentication
• Google Base
• Calendar
• Contacts
• Documents
• Picasa Web Albums
• Spreadsheets
• YouTube
