On the general Method forum, CF_Pro asked the question: "I noticed in the API you supportg PSIGate, and ElectraCash, but I do not see authorize.net.".
I'd like to keep the API questions on the API forum, so I have answered it here.
The current "live" version of the Method API does not support Intuit Merchant Services or Authorize.NET. We are currently testing out a labs version that has a unified payment gateway.
Test Site EndPoint: https://www.methodintegration.com/methodapitest/service.asmx
Service Function: MethodAPIActionRefundPaymentGateway
Gateway: supports value of either PSIGATE, ELECTRACASH, AUTHORIZENET or INTUITMERCHANTSERVICES.
Note: currently only electracash supports ACH. We plan on extending ACH to Authorize.Net and Intuit, so you see ACH fields in the unified payment gateway now, but they are currently ignored.
Note Also: the OverridePostURL is for Emulation, specifically Authorize.Net emulation.
Feel free to test it out and give feedback. Documentation updates will follow. I don't have date when we plan to make this lab version the default "live" version. We'll likely have a long incubation period.
