I'm running the C# Authentication Sample Project. For the EM URL I'm entering https://test2messaging.easylink.com/soap/sync. For the User ID and PasscodeI'm entering the credential I use to login to the EasyLink API Forum. I get "User authentication not accepted". Should I be using other credentials? We are only evaluating at this time so I don't have any other login information.
The credentials for the API Forum are not the same as the credentials for the test system (which is served by the test2messaging URL).
You will need to be in touch with your account team (sales or sales engineering) to arrange to have a test account provisioned for your use.
