1. API Description

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

This API is used to create a NAT Gateway.
Before taking actions on a NAT gateway, ensure that it has been successfully created, namely, the State field in the response of the DescribeNatGateway API is AVAILABLE.

A maximum of 100 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.
