Today at its mobile event, Facebook has just announced that it’s opening up its Write API and Search API to Facebook Places, in addition to the Read API that launched earlier this year.
So what does that mean? Facebook first launched its location APIs at its Places event in August, but it was split into two main sets of functionality: Read and Write access. Most developers only had access to the former — with a user’s permission, a third-party app could pull in Places data from Facebook. But only a handful of large partners had access to the Write functionality, which lets a user syndicate updates the other direction (for example, a check-in on SCVNGR also updates your Facebook Places status).
Now everyone has access to that feature — any app can use the API to write to Facebook Places.
