(Tcl) 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.
load ./chilkat.dll
# 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)
