Paypal Adaptive Payment types : Adaptive Payments provides several kinds of payment: Simple, Parallel, and Chained payments. Simple payments: Simple payments enable a sender to send a single payment to a single receiver. For example, your website can use an Adaptive Payments payment flow to transfer money resulting from a sale from your customer's PayPal account to your own account. This is the traditional kind of payment. Parallel Payments: Parallel payments enable a sender to send a single payment to multiple receivers. For example, your application might be a shopping cart that enables a buyer to pay for items from several merchants with one payment. Your shopping cart allocates the payment to merchants that actually provided the items. PayPal then deducts money from the sender's account and deposits it in the receivers' accounts. Chained Payments: Chained payments enable a sender to send a single payment to a primary receiver. The primary receiver keeps part of the payment and pays secondary receivers the remainder. For example, the primary receiver receives $100 from the sender's perspective. The primary receiver actually receives only $10 and passes a total of $90 to secondary receivers, Receiver 2 and Receiver 3.
