After a decade of helping sellers list items on eBay, power seller software maker Auctiva is launching its own marketplace. Or, more accurately, it's launching a platform, named AMP, where anyone can create a marketplace. Auctiva and its partners have 500,000 products ready to be included in any store via its API (our new AMP API profile).
The PayChannel API makes it possible to incorporate its credit card processing gateway into your software platform. Public information on the API is not available, though it does provide 8 payment features.
