1. API Description

Domain name for API request: es.tencentcloudapi.com.

This API is used for operations such as modifying node specification, renaming an instance, modifying configuration, resetting password, and setting Kibana blocklist/allowlist. InstanceId is required, while ForceRestart is optional. Other parameters or parameter combinations and their meanings are as follows:

• InstanceName: renames an instance (only for instance identification)
• NodeInfoList: modifies node configuration (horizontally scaling nodes, vertically scaling nodes, adding primary nodes, adding cold nodes, etc.)
• EsConfig: modifies cluster configuration
• Password: changes the password of the default user "elastic"
• EsAcl: modifies the ACL
• CosBackUp: sets auto-backup to COS for a cluster
  Only one of the parameters or parameter combinations above can be passed in at a time, while passing fewer or more ones will cause the request to fail.

A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: es.ap-shanghai-fsi.tencentcloudapi.com

2. Input Parameters
