Is it possible to call Elasticsearch API requests with the Logstash Keystore credentials that are stored (If they obviously are the right username/password/etc...).
I know API/curl calls can be done utilizing Username password or API Keys but what about from the Logstash server directory if they have a filled out keystore.
what would be the syntax?
Welcome to our community! 
Do you mean you want to run a curl and then use the details in the keystore?
I actually want to use the keystore values as the credentials used to run the curl against the API.
Something like
curl -u {$ElasticUser}:{$ElasticPassword} https://ElasticURL
