We're trying to make Salesforce send a message to one of our APIs through WSO2 API Manager 1.9.0. However, it seems that Salesforce is unable to authenticate and recommends using IP-restrictions.
So, is it possible to allow an anonymous/unauthenticated user to use an API in API Manager? IP-restriction I can take care of with firewalls, I don't have to do that in API Manager.
