There were, and still are, many gateway providers with APIs for payments. Authorize.net, NMI, USAePay, BrainTree, Payeezy, even Paypal was common enough once upon a time. And those are just a handful that I can list off the top of my head. (I know that some of those I listed have acquired each other recently as well.)
