While ES has its own API endpoints (see https://docs.splunk.com/Documentation/ES/7.0.0/API/AbouttheSplunkEnterpriseSecurityAPI), it mostly uses core Splunk APIs.  For correlation searches, use the savedsearches endpoints.

The saved/searches API documentation is at https://docs.splunk.com/Documentation/Splunk/8.2.4/RESTREF/RESTsearch#saved.2Fsearches .

As for which parameters are needed for a correlation search, I recommend using GET on an known correlation search to see which parameters are populated.
