Deprecation of Legacy Elasticsearch API (ES-API) Endpoints

Published: July 6, 2025

Effective: September 30, 2025

Deprecation notice

To improve platform stability, performance, and compatibility with modern observability tools, Coralogix will be permanently deprecating the old Elasticsearch API (ES-API) endpoints.

Action is required to ensure uninterrupted access to your log data.

Why this is happening

Two years ago, we transitioned Coralogix systems to fully operate with the OpenSearch API (OS-API). Since then, we've continued to support the ES-API endpoint to provide customers time to migrate. The time to complete this transition has come and the old ES-API endpoint will be fully shut down on September 30, 2025.

What’s affected

Any use of the following ES-API endpoints will stop functioning after the cutoff date:

https://coralogix-esapi.coralogix.com
https://esapi.coralogix.us
https://es-api.app.coralogix.in
https://es-api.eu2.coralogix.com
https://es-api.coralogixsg.com

This may impact:

Automation scripts using ES-API
Grafana dashboards sourcing data from Coralogix via ES-API
Ad-hoc queries or integrations built on the deprecated endpoint

What you need to do

To ensure continuity, customers must update both the endpoint URL and the authentication method:

STEP 1. Switch to the OpenSearch API

Refer to our documentation to find the new OpenSearch API endpoint for your environment.

STEP 2. Update authentication headers

Make sure to replace any old token header references in your scripts, tools,integrations, or dashboards:

Old: token: <your_api_key>
New: Authorization: Bearer <cx_api_key>

What happens after September 30, 2025?

The ES-API endpoints will be permanently disabled
Any services relying on ES-API will fail to fetch or display data
Grafana dashboards configured with ES-API will stop showing Coralogix logs
