Padraic Brady has posted about a new inclusion that Google has announced will be included in the authentication methods for their APIs - OAuth.

The Google Data API support comes with a few gotchas. Its documentation show a clear preference for using GET instead of POST, though the Google OAuth server does appear to natively support POST requests for everything with the exception that it has a small bug which interprets an empty POST request body as a sort of phantom empty parameter.

He notes that the library he's been working on (and submitted to both the Zend Framework and PEAR) it up to the 0.0.3 release including functionality marked as beta for the Consumer portion.
