Facebook is developing a "want" button feature which would allow users to mark retail items for purchase.
Developer Tom Waddington discovered the feature, which is currently disabled, as part of the Java developer kit Facebook offers. The button would function much like Facebook's "Like" button in which users express their interest or approval of a site, page or object.
Waddington later revealed that the developer kit also references a feature called "social context" in which users could view an item online and be provided with information on which friends have "liked" the item.
"I'm not entirely sure of the use case for this yet," Waddington wrote.
"Along with keywords, the plugin can use URLs, or a Facebook object_id, although these don’t appear to show any results."
The features could be part of a planned retail push for Facebook, allowing the company to leverage its social network with retail partners to help promote items or services.
In the wake of the company's initial public offering, analysts have noted that Facebook will need to open new revenue streams rather than relying solely on advertising. The company recently expanded its in-app purchasing platform and launched a storefront service for social application developers.
Despite a tumultuous IPO, Facebook has pressed forward with a plan which has included the purchase of facial recognition specialist Face.com.
