Creating Structuring Configurations (Recommended)

Function

This API is used to create structuring configurations using a structuring template, which facilitates parameter extraction and simplifies the parameter structure.

A user can call this API only once per second.

Calling Method

For details, see Calling APIs.

URI

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

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Definition Project ID. It can be obtained by calling an API or from the console. For details, see Obtaining a Project ID. Constraints N/A Range N/A Default Value N/A

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
Content-Type	Yes	String	Definition Message body format. Set this parameter to application/json;charset=utf8. Constraints N/A Range N/A Default Value N/A

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
