In Graylog, you can go to System → Data Nodes → Configuration where you can generate a client certificate to be used for authenticating against the data node’s Opensearch.
Alternatively, you can use the Graylog REST API which offers an endpoint proxying a subset of requests to the datanode’s Opensearch (POST /datanodes/{hostname}/opensearch/{path: .*}) .
