Hi Michael, Indeed the Opensearch REST client supports only basic auth at the moment. I don't know which sink are you using, but the streaming/connectors/opensearch/OpensearchSink provides the capability to configure the underlying client using RestClientFactory [1] so you could add the request / response interceptors to propagate OAuth2 tokens etc. This is not possible with other sinks yet but I think it should not be difficult to implement. If this is the case for you, could you please open the JIRA ticket?
Thank you.
