As Facebook prepares to transition control of the Marketplace classifieds application, which it created in 2007, to new partner Oodle, the Facebook Platform team has announced that the Marketplace APIs will be deprecated on March 3, 2009.

Back in December, Facebook announced that it has partnered with classifieds service Oodle to power a new version of the Marketplace application. Unlike other applications developed in house by Facebook – like Photos or Events – Marketplace never gained widespread adoption. While Facebook Photos and Facebook Events are more tightly integrated with users’ friends, Marketplace was primarily organized around Networks.

Oodle’s new service may launch as soon as next month, at which point new developer APIs may be available. “We hope to offer improved APIs and functionality at some point in the future,” the Facebook Platform team says.
