I am working with the relatively new Paypal REST api and have successfully been able to create billing plans, approve billing plans, get a list of my billing plans, create billing-agreements (subscriptions), execute billing-agreements, and find specific billing-agreements.
I would like to be able to retrieve (GET) a list of billing-agreements, similar to how I can get a lit of billing-plans. This is not shown in the documentation as being available. Does anyone know of a way of doing this? Since there is no webHook available for subscription cancellations (or any subscription events) and no way to get a list of agreements, this leaves developers with no efficient way to handle cancellations (especially since users can cancel via Paypal without visiting the site). My current method/plan to handle this is to loop through all subscriptions that I have stored in my MongoDB (I store them when they are executed successfully), and send a request to Paypal for that specific agreement. I check its 'state' and update my MongoDB if they don't match.
There must be a better way.
