Hi,
I need to get a fully completed and connected IPN (instant payment notification, similar to what PayPal has) PHP code for my website checkout system today or tomorrow (it's a bit urgent). The IPN code needs to work with the Click2Sell API. Here's a link with more information of the Click2Sell API:
[login to view URL]
Also, the code needs to use the "secret key" feature of the API, which passes an MD5 key to the Click2Sell server so that the transaction is fully verified.
Thanks!
I have looked over at the link you provided, as well as the details you specified in your post. I have constructed systems like this before. We can discuss this further in Private Message (if you're interested).
