There is a Paypal subscription mechanism which allows customers to be charged by a variable amount each month but I'm struggling to get info about it.
What is the mechanism known as? I can't google it because Paypal doesn't give it a consistent name. They variously refer to it as "automatic billing", "Variable amount subscriptions" and other random descriptions.
Is there a good source for info?
I created an HTML subscribe button. Can I now use the Express Checkout API to get info about the state of that subscription?
