We've been using your "https://api2.authorize.net/soap/v1/Service.asmx" service for some time to do CIM integrations. We are a .NET shop and have simply added a "service reference" to the URL above to our project. Recently I noticed we can no longer use the "Update Service Reference" command in Visual Studio, as we get a 500 error.
We also cannot add this URL as a "Service Reference" to new project without getting the same error.
This was not a problem in the past, as we were able to do this a month ago.
A workaround to add the service reference is to add as the following...
https://api2.authorize.net/soap/v1/Service.asmx?wsdl
Any idea why we can no longer add the reference without the wsdl parameter? Looking on the web, this seems to be a common problem if the ASMX service does not have the following in the web.config (or server.config)...
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
Could this be the issue?
