## Notes ##

Some common endpoints to consider providing:

* Transactional Email Service:
    * Unsubscribe
        * eg: a link that automatically unsubscribes them, then depending on whether it has ajax headers or not redirects them to a page saying you have been unsubscribed.
    * Particular service no longer required (not unsubscribing, but no longer need tips, thanks).
* Payment services:
    * Payment accepted endpoint -- activate the service.
    * Subscription coming to an end
    * Credit card expiration coming up
    * Refund requested via Payment service
