PayPal IPN

Hi,

I have just signed up to paypal pro payments and want to get this set-up on my site.

What i want to do is have a form where the customer can fill in their credit card details and when the user clicks pay now then it will check with paypal without going off my site to see if the payment is valid or not.

I have seen quite a few classes which i think do this but want to know your opinion on the best way to set this up and also what script to use if you have done this before and used a script.

Cheers,
Adam

I am no expert here, but I think you are getting into a very sticky and difficult area. My former wife set up an online shop using earlier and it was an enourmously difficult task to get a portal that would accept payments via credit cards.

You must realize that any transactions containing sensitive information like credit card information must be done in a very secure manner, using ssl encrypted code (https vs. http), etc. You would have the burden of ensuring that your code is developed securely, and that no credit card information is stored anywhere on your own servers (what if you are hacked?).

But perhaps more importantly, I do not think that Paypal would allow you to supply their site and functionalities with credit card information of your customers. For security reasons. Perhaps it is possible for you to see if Paypal has some sort of secure portal you can link your site to?

Actually, PayPal certainly offers this functionality. It's called PayFlo Pro and it allows you to process credit card info from you site without having to leave. As long as you use SSL it's plenty secure, and the programming of it isn't that difficult. You simply make one request to PayPal over a secure connection supplying the credit card info and all other important details, and pay pal processes the transaction, and gives a response as to wether it was successful or not.
