Facebook has announced that Facebook Credits has officially left beta test mode. Furthermore, they’ve announced that games that use in-game purchases will be required by Facebook to make the switch to Facebook Credits by July 1.

According to Facebook Credits product manager Deb Liu, 150 developers were using Facebook Credits in 350 applications during the beta, and represented more than 70 percent of all the virtual goods purchases on the social network. Deeper integration will come, which will allow virtual goods to be directly purchasable via Credits.

Facebook takes a 30 percent cut of all transactions using Credits.
