Receives an FLG 360 webhook and adds a subscriber to a MailChimp list.

FLG 360 Webhook to MailChimp List.coffee

# CoffeeScript
###

This script receives a webhook from FLG 360 and adds the lead's email address to MailChimp.  Here's how to use:

1. In FLG 360, go to 'Settings > Lead Groups > Lead Types > Edit' and add a webhook to this script's webhook URL (below) on any event ('Received' for example).
2. Type in your MailChimp list name (case sensitive).
3. Authorize your MailChimp account by clicking the red 'Authorize' button.
4. All done, switch the script on and trigger the event in FLG 360 to make sure it works.
