I've been fighting with paypal's documentation for a few days and I have several doubts about how it could fit my needs.
In the site we are developing, we need to handle subscriptions, and we are going to sell items. In order to bill those items there are three cases:
1- The item can be sold with one-time payment method.
2- The item is going to be billed recurrently (once per month, per year, per week,...)
3- The item needs to be billed base on its usage (some kind of pay-as-you-go system)
I was considering to use "Recurring Payments with Express Checkout API" which aparently can handle this situation perfectly. Now, there is one problem. I understand Paypal sends notifications to the buyer, and to us, when the recurring payment occurs. This is ok for accounts's suscriptions, however, in the items case could be annoying for the client to have one notification for each item is going to be billed in the same period. For example, one buyer has 4 items which have to be billed every month on 25th. The desirable thing would be to have one notification with a summary of the items have been billed. Is this possible using Paypal Recurring Payments with Express Checkout API?
Thanks in advance!
