(Ruby) PayPal - Create Direct Credit Card Payment

Creates a direct credit card payment where your application passes the credit card, shipping, and payment information to PayPal.

Note: For sandbox calls, you can use the credit card numbers provided in your sandbox test accounts.

Note: This is an example where you handle the card data directly, and therefore you would need to ensure you are PCI compliant. There are other ways to create a payment where your application does NOT handle the credit card data directly.

Note: This example requires Chilkat v9.5.0.64 or greater.

# Note: Requires Chilkat v9.5.0.64 or greater.

# This requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Load our previously obtained access token. (see PayPal OAuth2 Access Token)

# Make the initial connection.
# A single REST object, once connected, can be used for many PayPal REST API calls.
# The auto-reconnect indicates that if the already-established HTTPS connection is closed,
# then it will be automatically re-established as needed.

# ----------------------------------------------------------------------------------------------
# The code above this comment could be placed inside a function/subroutine within the application
