Question: Authorize.net process payment request but in HC showing unpaid ?
At HC host level path
"Billing System :: Integrate / Edit Payment Gateways :: Configure
Gateway :: Edit Authorize.Net"
In "Response Parser URL" make sure it is not set with localhost i.e http://localhost:8787/GatewayScripts/Authorize.Net.asp
it should be http://HCPanelURL/GatewayScripts/Authorize.Net.asp
Where 'HCPanelURL' = The live URL from which you access the HC panel it could be http://yourdomain.com/admin or http://yourdomain.com:8787
