I was looking for a reference on how to set up a payflow pro or a paypal pro in my website. I have read lot of guide in setting already but I cannot find the right SDK for Paypal Pro. I also check the SDK downloads of Paypal but they dont have SDK for Payflow Pro using PHP. If you know a link where to download the SDK in setting up the Payflow / Paypal and its user guide is very much appreciated. Also please share your idea if you have set up PayFlow / Paypal Pro already so that it will help fix my problem.
