I’ve finally added both PayPal Pro and Authorize.net support to YAK — which means users who don’t want to redirect their customers to an external site (ala PayPal Standard and Google Checkout), can now provide a more seamless payment process.

If anyone is interested in testing this functionality, please let me know (see the Contact page). I can provide basic setup/configuration information, but you’ll probably need to read the requisite integration docs for whichever gateway you want to test.
