Battle of payment systems for web design

Just as Amazon rolls out it's new payment API system, Flexible Payments Service (FPS), Paypal counter attacks with it's own flexible payment API, Adaptive Payments, which gives web designers more control and access to the Paypal system for building applications. The payment systems, which handle payments sent between a sender of a payment and one or more receivers of the payment, are very similar in functionality.

Micropayment support:
Adaptive Payments by Paypal has micropayments support--Flexible Payments Service also does.

Payment Aggregation:
Both APIs will allow developers and designers to become payment aggregators.
