Google Documents List API

What is the Google Documents List API?

The Google Documents List API allows client applications to programmatically access and manipulate user data stored with Google Documents. Here are some of the things you can do with the API:

Discovery Retrieve documents that match specific keywords, categories, or metadata.	Download export documents in common formats such as pdf, rtf, doc, xls, ppt, and more.
Sharing (ACLs) Modify the sharing permissions of documents and folders. The API allows sharing to individuals, group emails, or across an entire Google Apps domain.	Create/upload/copy documents Create online backups of local word processor documents, spreadsheets, presentations, and PDFs.
Revisions Review, download, or publish a document's complete revision history.	File documents Create folders and move documents/folders in and out of folders.
Spreadsheets: While the Documents List API can be used to create and retrieve a list of Google Spreadsheets, it cannot be used to modify the data within a Spreadsheet. For that, you can use the Google Spreadsheets API.
