Blasting Cap

I have an application that needs to use Paypal to verify the legitimacy
of a credit card, not the actual charge.

The only thing I can find thru Paypal's SDK is stuff that's a COM add-in.

Is there a web service that anyone knows of that'll do this process?
One that would be free or a single-time fee would be preferable.

Any help appreciated.

Hi,

Why don't you consider wrapping the com component? A few second works and
free (although, of course, you would be stuck with some unmanaged code).

Hope this helps.
Regards.

There is a validate card method that you may be able to integrate in
your project.

You can Mod10 check the card and make sure date is in the future. Beyond
that, you have to run an authorization. PayPal pro can do this, but it is a
pay service. I know of no "check for valid card" free or one-time fee
services.
