Prerequisites
You need an Elasticsearch cluster (self-hosted or Elastic Cloud) and an API key or username/password with index and write permissions.Connection Setup
1. Host URL
Enter the Elasticsearch host URL (e.g.https://my-cluster.es.us-east-1.aws.found.io:9243).2. Authentication
Use an API key (recommended) or basic authentication (username and password). Create an API key in Elasticsearch Security → API Keys.3. Index Name
Enter the index name. Documents will be written to this index. The index is created automatically if it does not exist.Upsert Key
The upsert key field maps to the document identifier (_id) used for document updates. When a document with the same ID already exists, it is updated instead of creating a duplicate.
