Example 3: Creating Dual VPN Connections
Scenario
This section describes how to create dual VPN connections by calling APIs.
Prerequisites
- You have created a VPN gateway. For details, see Creating a VPN Gateway.
- You have created a customer gateway. For details, see Creating a Customer Gateway.
- 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.
The token obtained through IAM is valid for only 24 hours. When using a token for authentication, cache it to avoid frequent calling.

Procedure
- Create a VPN connection in static routing mode for a VPN gateway associated with a VPC.
- Send POST https://{endpoint}/v5/{project_id}/vpn-connections/batch-create.
- Add X-Auth-Token to the request header.
- Specify the following parameters in the request body:
{ "vpn_connections": [ { "vgw_ip": "e4d7930f-demo-4cbf-b78a-b004416c7485", "cgw_id": "8916effb-demo-42d8-83d7-4517567d3d26", "vgw_id": "8030f6d6-demo-4d20-a7f8-50a7a826e2f8", "peer_subnets": [ "192.168.44.0/24" ], "psk": "abcd****" }, { "vgw_ip": "1fb97767-demo-4d8b-83bb-6f878f662005", "cgw_id": "8916effb-demo-42d8-83d7-4517567d3d26", "vgw_id": "8030f6d6-demo-4d20-a7f8-50a7a826e2f8", "peer_subnets": [ "192.168.44.0/24" ], "psk": "abcd****" } ] } - Check the response.
