How to Connect with OpenVPN (TCP/UDP) via APIs

OVPN (OpenVPN) is a versatile VPN protocol known for its flexibility, reliability, and robust security. Integrating OVPN into your application using APIs can enhance your application's network security and performance. This guide provides a detailed technical overview of how to connect with the OVPN protocol via APIs.

Overview

OVPN (OpenVPN) is designed to be highly configurable, making it an excellent choice for VPN implementations. Using APIs to manage OVPN connections can automate and streamline the process of establishing secure connections. This article covers the steps necessary to connect with the OVPN protocol via APIs.

Prerequisites

Before proceeding, ensure you have:

• API Access: Credentials and access to PureWL APIs.
• OVPN Client: Installed OpenVPN client software on the device.

Steps to Connect with OVPN

By following the steps outlined in this guide, you can seamlessly integrate OVPN into your application, automate VPN connections, and ensure a robust and secure networking experience.

1. Get Access Token using the API to get an access token required for authentication. – Get Access Token
2. Get Optimized Server using the following API – Get Optimized Server
   • Request parameters:
     • X-AccessToken: You can get this from the following API – Get Access Token
     • sCountrySlug: You need to add ISO2 code from your allocated locations – Get Subscribed Countries
     • sProtocolSlug1: You need to send “TCP” or “UDP” as a value
     • iMcs: Pass the value as "1".
     • sDeviceType: You can simply add “Android” here
     • sUsername: You can get it in response from Generate VPN Account
3. Parse Configuration
   • In response from the Get Optimized Server API, you will receive a server with a configuration file.
   • Parse this configuration file to the OVPN client application.
4. Create and Connect Tunnel
   • Using the data from the configuration file, create a new tunnel in the OVPN client application.
   • Connect to the OVPN server using the configured tunnel.

By automating these steps, you can integrate OVPN (TCP/UDP) into your application, providing secure and reliable VPN connections for enhanced network security and performance.
