API requests for Google Documents List, Google Spreadsheets, and Google Sites will be required to use secure sockets layer connections.
Google this week announced that it will soon begin requiring secure sockets layer (SSL) encryption to use more of its products, and in particular for the APIs that developers call to access Google's products and services.

Starting on September 15, "Google will require that all users of Google Documents List API, Google Spreadsheets API, and Google Sites API use SSL connections for all API requests," said Adam Feldman, who's part of the Google developer team, in a blog post. In other words, all calls will have to be made to an HTTPS address. Any HTTP requests will be rejected.
