We are looking for API request which fetch the audit logs/events performed by users in various application
Hi
unfortunately (at least I don't know) that there is separate endpoints to get splunk audit logs.
But you could get those by using search endpoint. https://docs.splunk.com/Documentation/Splunk/9.1.2/RESTREF/RESTsearch
Just create some saved searches which give you needed information and then call those or use ad hoc queries over REST api.
