I am going to setup a merchant account. One of the merchants I am looking at uses Quantum Gateway instead of Authorize.net. They can add authorize.net but there are more fees associated with adding it.



I talked to the sales representative who informed me that the quantum gateway has APIs that work in place of an Authorize.net API. Does anyone know if I can use an API from another gateway? Or does e-junkie only work with Authorize.net APIs?
