Ling’s departure, which was reported by VentureBeat’s Eric Eldon and BoomTown’s Kara Swisher, was confirmed by Facebook in a statement Tuesday.

At the Graphing Social Patterns: East conference in June, Ling confirmed that Facebook would be launching a widely rumored payment system for application developers, but declined to provide a time frame at the conference. Before joining Facebook last fall, Ling was the head of Google Checkout.

Ling’s move to Facebook was followed by that of Elliot Schrage, vice president of global communications and public affairs at Google. Apparently there was some speculation that Ling wasn’t happy with Schrage being installed over him at Facebook, but Ling denied that rumor to Swisher, saying, “I have huge respect for Elliot and work well with him.”

Ling, who told his staff about his departure Tuesday, told Swisher that he was leaving the social-networking site to pursue “another opportunity.” He added that, “Facebook is a tremendous organization and I would not leave it if it were not for a great opportunity.”

Facebook’s statement on the departure:

Facebook confirms that Ben Ling will be leaving the company in the coming weeks to pursue other interests. We wish him well and appreciate his great contributions to the early success of Facebook Platform. Platform is poised for continued growth and success and the company is on track to deliver the range of major initiatives announced last month at f8, including Facebook Connect, fbFund and the Great Apps and Application Verification programs. Each of these programs have a strong team of professionals focused on attracting the best developers to Facebook Platform, helping developers succeed on Platform, and helping users find and enjoy great applications on Facebook.

Ling’s is the fourth key executive to leave Facebook in recent months: Owen Van Natta, Facebook’s chief revenue officer and vice president of operations, announced his departure in February; Matt Cohler, Facebook’s employee, left for venture firm Benchmark Capital in June; and Adam D’Angelo, Facebook’s chief technology officer, announced in June he was leaving the company to take some time off.
