AS2 shopping cart and PayPal Web Pro integration

[FONT=Arial][SIZE=2][COLOR=#080000] [/COLOR][/SIZE][/FONT][FONT=Arial][SIZE=2][COLOR=#080000]I am familiar with communicating to PayPal Web Standard Payments from AS2, but not the API functions of Web Pro Payments. The php files I have are merely copies of php files I download from PayPal. Based on my readings, Web Pro API requires two payment options: Direct Payment and Express Checkout. Each option requires three separate php files. [/COLOR][/SIZE][/FONT]
