Today in APIs: Facebook Credits, LinkedIn Acquisition and 7 New APIs

Many game developers aren't seeing the increase in conversions or revenue they hoped for from the Facebook Credits API. LinkedIn has acquired API-happy Rapportive. Plus: financial data challenges, API vs. RSS and 7 new APIs.

Facebook Losing Credit With Game Developers

It seems Facebook Credits isn't helping developers make money like expected:

Facebook made it mandatory for developers to use its payments Platform in canvas games in July. That meant developers on the platform had to start handing over a 30 percent revenue share to the company, mirroring a similar split on Apple’s iOS. The hope was that a single, universal currency would make it more frictionless for users to start paying for virtual goods.

"We thought that conversions would go up and be around 15 or 20 percent," said Kevin Chou, the chief executive of Kabam, a social gaming company that targets a more hardcore demographic, at the Inside Social Apps conference in San Francisco. "But it turned out to be around 5 to 10 percent, meaning that we’re taking a 20 percent net tax."

LinkedIn Acquires Inbox-Augmenting Rapportive

AllThingsD describes the service:

Rapportive, which is still available only for Gmail, overlays an email correspondent’s social networking accounts alongside open messages and drafts. So, for instance, you can see a person’s most recent tweet and mention it in your email to them. Or you can realize that you’re not connected on LinkedIn to a person you just had a meeting with, and rectify that.
