Thanks in advance.
I use this is very easy without encryption. You must see the API and any variable you want to set put it in the PayPal url. header("Location: https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=YOUR_EMAIL&lc=US&button_subtype=services&no_note=0&cn=Add special instructions to the seller:&no_shipping=0&rm=1&return=http://YOUR_SITE&cancel_return=http://YOUR_SITE¤cy_code=USD&bn=PP-BuyNowBF:logo.png:NonHosted&item_name=ITEM_NAME&item_number=1&amount=1"); PHP:
