Details on how to connect with Amazon OpenSearch service via HTTP.

Version:

all.

What other resources are available?

AWS documentation on Fine Grain control for OpenSearch states the following:

If you create a master in the internal user database (with a username and password combination), you can use HTTP basic authentication (as well as IAM credentials) to make requests to the cluster. Most clients support basic authentication, including curl, which also supports AWS Signature Version 4 with the --aws-sigv4 option. The internal user database is stored in an OpenSearch index, so you can't share it with other clusters.

However the OpenSearch documentation doesn't detail how to connect via HTTP to Amazon OpenSearch Service.
