Plugin is attempting to use deprecated and undocumented API. There is a documented API you can use.

Hi there,

We're getting support requests at 6Wunderkinder asking for "api keys" from users of Airmail trying to use your plugin.

We have completely turned off the Wunderlist 2 api which this code is attempting to use, which is why it no longer works.

We have a documented API that you can use, just send us an email with from your Wunderlist email to api@wunderlist.com so we can add you to the beta program.
