PUT _license

POST _license

If Elasticsearch security features are enabled, you need manage cluster privileges to install the license.

If Elasticsearch security features are enabled and you are installing a gold or platinum license, you must enable TLS on the transport networking layer before you install the license. See Encrypting communications in Elasticsearch.

You can update your license at runtime without shutting down your nodes. License updates take effect immediately. If the license you are installing does not support all of the features that were available with your previous license, however, you are notified in the response. You must then re-submit the API request with the acknowledge parameter set to true.

For more information about the different types of licenses, see https://www.elastic.co/subscriptions.

The following example updates to a basic license:

PUT _license
{
  "licenses": [
    {
      "uid":"893361dc-9749-4997-93cb-802e3d7fa4xx",
      "type":"basic",
      "issue_date_in_millis":1411948800000,
      "expiry_date_in_millis":1914278399999,
      "max_nodes":1,
      "issued_to":"issuedTo",
      "issuer":"issuer",
      "signature":"xx"
    }
    ]
}

You can also install your license file using a curl command. Be sure to add @ before the license file path to instruct curl to treat it as an input file.

curl -XPUT -u <user> 'http://<host>:<port>/_license' -H "Content-Type: application/json" -d @license.json

On Windows, use the following command:

Invoke-WebRequest -uri http://<host>:<port>/_license -Credential elastic -Method Put -ContentType "application/json" -InFile .\license.json

In these examples,

If you previously had a license with more features than the basic license, you receive the following response:

  {
  "acknowledged": false,
  "license_status": "valid",
  "acknowledge": {
    "message": """This license update requires acknowledgement. To acknowledge the license, please read the following messages and update the license again, this time with the "acknowledge=true" parameter:""",
    "watcher": [
      "Watcher will be disabled"
    ],
    "logstash": [
      "Logstash will no longer poll for centrally-managed pipelines"
    ],
    "security": [
      "The following X-Pack security functionality will be disabled: ..." ]
    }
}

To complete the update, you must re-submit the API request and set the acknowledge parameter to true. For example:

PUT _license?acknowledge=true
{
  "licenses": [
    {
      "uid":"893361dc-9749-4997-93cb-802e3d7fa4xx",
      "type":"basic",
      "issue_date_in_millis":1411948800000,
      "expiry_date_in_millis":1914278399999,
      "max_nodes":1,
      "issued_to":"issuedTo",
      "issuer":"issuer",
      "signature":"xx"
    }
    ]
}

Alternatively:

curl -XPUT -u elastic 'http://<host>:<port>/_license?acknowledge=true' -H "Content-Type: application/json" -d @license.json
