Authentication

Amazon OpenSearch Service

Requests to OpenSearch Service and OpenSearch Serverless must be signed using the AWS signing protocol. Use AwsSdk2Transport to send signed requests.

SdkHttpClient httpClient = ApacheHttpClient.builder().build();

OpenSearchClient client = new OpenSearchClient(
    new AwsSdk2Transport(
        httpClient,
        "search-...us-west-2.es.amazonaws.com", // OpenSearch endpoint, without https://
        "es" // signing service name, use "aoss" for OpenSearch Serverless
        Region.US_WEST_2, // signing service region
        AwsSdk2TransportOptions.builder().build()
    )
);

InfoResponse info = client.info();
System.out.println(info.version().distribution() + ": " + info.version().number());

httpClient.close();
