1. API Description

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

This API (DescribeLifecycleHooks) is used to query the information of lifecycle hooks.

You can query the details of lifecycle hooks based on information such as auto scaling group ID, lifecycle hook ID, or lifecycle hook name. For more information on filters, see Filter.
If the parameter is empty, a certain number (specified by Limit and 20 by default) of lifecycle hooks of the current user will be returned.

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

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
This document describes the parameters for Signature V1. It's recommended to use the V3 signature, which provides higher security. Note that for Signature V3, the common parameters need to be placed in the HTTP Header. See details.
