Hi, Is there a limit for how big an invoice can be? I'm builiding a
system that would process invoices of around $5000, and would like to
know if this could be an issue. Thanks!
They have a SOAP service, adding it into a .NET solution is extremely
easy, and their documentation is really thorough. You can download it
from http://www.authorize.net/support/CIM_SOAP_guide.pdf
