-- This is a "Simple Payment" which means there's a single sender
-- and receiver (same as Withdrawal).

-- It uses the "Explicit" payment approval type, meaning the payer must go to
-- PayPal in their browser to approve the payment. Here's an example payment
-- approval URL with a PayKey of "foo":
