Custom Cart Options

All:

I have built a custom product gallery using Flash, and want to add the ability to purchase each product. I will handle building the shopping cart, registration/login, and checkout process within the flash application, and just want to submit the final payment via an API to a merchant account which would return a pass/fail on the payment to me.

I don't want to have a third-party branded checkout process (like what i've found so far on PayPal or Google Checkout), and want to keep as much as possible within my Flash interface with the payment just processed behind the scenes.

I would also want to minimize costs, and would like to stick with a service that only has fees per transaction.

What are my options here, and does anyone have any recommendations on a good service to use for this?

Thanks,

I'm not aware of any "transaction-only" payment providers, but what you're probably looking for is a "SOAP interface".

That would allow you to call the payment processing from within your app.

Also you could consider a PHP cURL interface to load the payment processing page in the background, commit the transaction, and report the status to the Flash app.

As Flash can call PHP, it's just like using any other PHP compatible payment processing system.

As for names of providers... sorry, I can't help there. I've usually used Worldpay, or if clients choose, Paypal or Google Checkout.

Cheers,
Karl

some quick research on Zen Cart's website don't show promise that it has a usable API to just handle the transaction via backend calls. I might be missing something, as there's tons of docs/forums.

I did find this third party app, which looks promising:
