Hello,
I found that Chang Sau S.'s ruby-paypal library can use Mass Payment
(
http://ruby-paypal.rubyforge.org/) to automatically send money to any
PayPal
recipient. What's confusing is that the RDoc on the site is from an
older
version that did not support Mass Payment.

Some older (2006) threads mention they want this, but they were never
resolved. I hope this information will be useful to people that still
don't
have the answer to this.

 == Unofficial guide to sending automatic payments with Ruby

   1. gem install ruby-paypal
   2. require 'ruby-paypal' at the top of your file
   3. Use this example code for a single transaction or create your own:

# Credentials found in environment files.
pp_nvp = PaypalNVP.new(PPG_API_USERNAME, PPG_API_PASSWORD,
PPG_API_SIGNATURE)
# def do_mass_payment(payments, email_subject,
receiver_type='EmailAddress',
currency_code='USD')
payments = []
payments[0] = PayPalPayment.new
payments[0].email = self.email
payments[0].unique_id = 1239829
payments[0].note = "Note"
payments[0].amount = Money.new(self.current_value)
# Make the call.
response = pp_nvp.do_mass_payment(payments, "Email subject line")
# Update our own administration.
if response.ack == 'Success'
# Do success stuff here
end

A sidenote:
I could not get the ruby-paypal and the paypal (by Tobias L.) gem to
work on the same Rails installation - they both use a class called
Paypal. I
fixed this by including ruby-paypal in my vendor/ dir and renaming the
class
Paypal to PaypalNVP. The Money library is included with the 'paypal'
(NOT
the ruby-paypal) gem.
