Salesforce provides Mutual Authentication Certificate for inbound calls. These certificated are provided by external systems from where request will come into the salesforce and we upload it in salesforce system. I just want to know that how does salesforce validate this certificate for inbound request. What is the mechanism for it.
P.S:- Suppose we have exposed our web service for multiple external systems and all these systems provided their own certificates to salesforce. Now how salesforce validate certificate corresponding to the individual external system.
