2944066 - You cannot Complete Third-Party Logistics Integration Scenario due to the Error message: 'Invalid authentication method'


You are trying to implement the Third-Party Logistics Integration Scenario, and have set up the relevant Communication Arrangement. You select the Authentication Method: None, since your Third-Party Logistics Provider uses an Office 365 Webhook to collect the data, which does not require an authentication with either a certificate or username/password.

However, when you perform Check Completeness, the system displays the error message: 'Invalid Authentication Method'. Now you want to know if the Authentication Method “None” is a valid option for the Third-Party Logistics Integration Scenario.
