Function

This API is used to modify structuring configurations using a structuring template.

Calling Method

For details, see Calling APIs.

URI

PUT /v3/{project_id}/lts/struct/template

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain a project ID, see Obtaining the Project ID, Account ID, Log Group ID, and Log Stream ID. Minimum: 32 Maximum: 32

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Definition User token obtained from IAM. For details about how to obtain it, see Obtaining a User Token. Constraints N/A Range N/A Default Value N/A
