Interacting with the Trello API will require the use of HttpService. There probably are resources out there that help you (such as the Trello API thread that you included), but a simple Google search or even a DevForum search can lead you to that.
I reccommend using this API, if you have any scripting experience. It’s not that hard to use, you can see examples in the example script. Hope this helps:
