While integrating the blogs using wordpress plugin in one of the project I am working on. I observed that using current version(0.1) of wordpress plugin, when we request for recent posts, it returns not only published blogs but also blogs with status as draft(which are not yet published). Along with that, we needed to show excerpt of recent blogs. So the workaround I found is given below<\/p>\n
