Example 1: Creating an S2C VPN Gateway

Scenario

This section describes how to create an S2C VPN gateway by calling an API.

Prerequisites

  • You have determined the region where the VPN gateway is to be deployed and obtained the endpoint for calling APIs based on the region.
  • You have obtained a user token if you need to use token authentication. In addition, you need to add X-Auth-Token to the request header when calling an API. For details about token authentication, see "Authentication" in the Virtual Private Cloud API Reference.

The token obtained through IAM is valid for only 24 hours. When using a token for authentication, cache it to avoid frequent calling.

Data Preparation
