Who should use the Google Documents List API?
The API is designed to help anyone interested in uploading their existing documents to their Google Documents account programmatically and for developers wishing to integrate their applications with Google Documents. If you have not created a Google Documents account please visit http://docs.google.com. If you wish to create an application which can programmatically upload to or access your list of documents, then the Google Documents List API can enable you to do so. Developers should be familiar with XML and the HTTP protocol. Further information on how to begin can be found here: http://code.google.
