IFTTT or SlackBot charge triggers?


I’m wondering if anyone has cobbled together a GTBee-like recipe using either the IFTTT or the SlackBot charge triggers? The idea is to trigger a one-off charge if you don’t do a task by the due-date, (rather than setting up a Beeminder goal to regularly complete tasks or such).
