To use the AnyGatewayPaymentProvider all you need to do is copy the Commerce.PaymentProvider.dll file in your /bin directory, follow the instructions in the Web.ConfigSetup.txt file, and install the IBiz E-Payment Integrator (Trial included). 

This payment provider makes use of the IBiz E-Payment Integrator which consists of fully-managed ASP.NET components for credit card and electronic check (ACH) processing via major Internet Payment gateways.  More information can be found at the /n software website at http://www.nsoftware.com/ibiz/epayment/. 

If you are working with the source code you can include the AnyGatewayPaymentProvider.cs file in the Commerce.PaymentProviders project.  Then make sure to include a reference to the newly installed IBiz E-Payment Integrator and recompile.

Please direct any technical questions about the provider to ibiz@nsoftware.com.

Happy Coding!
