I would like to setup a simple PayPal button on my website, however I need to send and receive a few custom parameters.
I have generated some basic button code: (eg https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=MXR9J7XQ4SW3N)
I need to pass and receive back 2 parameters: - Customer_ID - Product_ID
Usually I would do something like this: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=MXR9J7XQ4SW3N&*Customer_ID=1&Product_ID=1*
But I would I receive those parameters back after the payment is complete?
Many thanks for your help.
