Warren_Brill - I recommend putting in the received error as well, to make debugging a bit easier. But after a quick look at your queries, I'm sure you use a wrong attribute blog.id. <#assign articleList = "SELECT * FROM messages WHERE blog.id IN '${whiteList}'" /> The messages resource of APIv2 doesn't have any attribute named blog. You should replace blog.id with board.id: <#assign articleList = "SELECT * FROM messages WHERE board.id IN '${whiteList}'" /> See description of the board attribute below: "The board in which the message appears. A board can be of type: forum, tkb, qanda, blog, idea, contest, group, or review. The conversation style is derived from the board type of the board that contains the message." For information see message resource docs.
