I have to link to the Authorize.Net Payment Gateway through events on Facebook. Each event will be created using the SimpleCheckout feature, but inorder for this to actually work, I have to have an actual URL to paste onto the Facebook eventpage - not an input button with a value.

i.e.

secure.authorize.net/124252454/

or whatever. As long as it's a unique URL and it's linkable. Can it be done using SimpleCheckout or would you recommend another solution or method?

Thanks!
