Credit card processing controls

[Daniello]

Hello!
I am looking for any credit card processor for Delphi/Lazarus, to integrate with one of my apps.
Basically I need something that allows users to pay with creditcard, in order to unlock features in the app.
Tried to google it a lot, could not find anything (maybe not using the right keywords?)

Anyone knows of something like this?

That's a service given by your bank and every bank has its own api to use talk with your bank and see what you can do or use any other online service that supports that.

But there must be some service that allows apps to process payments, like Paypal works, but Paypal as far as I know cannot be used by desktop apps

I think they have a WebService you can consume from your app like Amazon has. Try googling "paypal WS" without the double quotation.

I googled that, thanks, that will do
Also it seems that there are already some premade solutions for Delphi, but well, expensive, at 400$ or more, I will try to roll my own

It doesn't have to be a bank server. There're special payment services aka merchants.

(for US/Canada):
Authorize.NET http://developer.authorize.net/
Bluepay http://www.bluepay.com/developers
Solupay http://www.solupay.com/Products_and_Services/Credit_and_Debit_Card_Processing
... and more?

The implementation for each of these is extremely trivial HTTPS WebService call.

Could be done within a day using... let's say Synapse library.

I see, thanks for your input, did not know about these.
Seems that it requires payment to use their services though, and in other hand, I think Paypal service is free (well, might have a little % fee per payment I guess, but that is ok for me)
