What is Wunderpy?¶ Wunderpy is a python package that aims to provide access to the Wunderlist API. As of this writing (9/13), Wunderlist doesn’t have a public, documented API. This means that I’ve had to rely exclusively on reverse engineering the Wunderlist application (OS X Desktop) to figure out how to use it. Thus, it’s quite possible that things will change unexpectedly and break everything.
