Hello, I have noticed that the integration is throwing errors when an opp is closed won even though we are not using that functionally. The error is:

Failed to invoke future method 'public static void callout(String, String)' on class 'ifttt.Webhook' for job id 'XXXXXX'

caused by: System.CalloutException: Unauthorized endpoint, please check Setup->Security->Remote site settings. endpoint = http://ifttt-salesforce.herokuapp.com/ifttt/v1/webhook/opportunity_was_won

While I know how to resolve the issue (By adding the site into the site settings). I am a bit confused as to why IFTTT is trying to use that endpoint considering that I do not have anything setup for Opps for that trigger to fire (Also concerned about it using an HTTP endpoint instead of an HTTPS one)

Does anyone have any insight into this?
