trying to add "external web service" for a solution and it gives me
"Something went wrong. Please contact your administrator."-error.
We are using Salesforce3.wsdl .
Currently Salesforce.WSDL are not supported with Evolve version 20.1.
Salesforce.wsdl, means calling SalesForce SOAP services. That may not work, as we only support Anonymous and Request Headers key value authentication with version 20.1.
Evolve 20.2 will support REST API calls to sales force.
