Deprecation of legacy elasticsearch API ES-API endpoints

Published: July 6, 2025

Effective: November 10, 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 November 10, 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

Choose the https://api./data/os-api endpoint that corresponds to your Coralogix domain using the domain selector at the top of the page.

Region	Legacy	New
EU1	https://coralogix-esapi.coralogix.com	https://api.eu1.coralogix.com/data/os-api/
US1	https://esapi.coralogix.us/	https://api.us1.coralogix.com/data/os-api/
AP1	https://es-api.app.coralogix.in/	https://api.ap1.coralogix.com/data/os-api/
EU2	https://es-api.eu2.coralogix.com/	https://api.eu2.coralogix.com/data/os-api/
AP2	https://es-api.coralogixsg.com/	https://api.ap2.coralogix.com/data/os-api/
AP3	https://es-api.ap3.coralogix.com	https://api.ap3.coralogix.com/data/os-api/

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 November 10, 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
