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.comhttps://esapi.coralogix.ushttps://es-api.app.coralogix.inhttps://es-api.eu2.coralogix.comhttps://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
