How to connect to Amazon OpenSearch Service?

Hi @Kenny
First I followed this document(Elasticsearch Integration) to connect to Amazon OpenSearch Service.
But I got two errors.

  1. No Living connections
  2. Unable to connect. Error: Authorization Exception

Then I tried to use the API to connect to Amazon OpenSearch Service.
Here is what I set in the API.


But I got an error as below.

It seems the API resource put the authorization in the URL. But the Amazon OpenSearch Service needs authorization in the header.

Do you have any advice for this?
