Happ VPN Key Settings and How to Use Them
The Happ app is built on Xray-core and exposes a handful of settings that shape speed, stability, and which apps actually route through the VPN. Once you understand them, you can quickly adapt your connection to a specific task — from work tools to streaming and gaming — without reinstalling anything. Below is a walkthrough of what each setting controls and how they work together.
Choosing a server
The server is the first thing to check when a connection feels slow or unstable. Happ lets you switch between available servers directly in the app, using latency to the target region as your guide. A full breakdown of the server list and how to judge response times is on the /en/servers/ page, along with recommendations for different use cases.
Protocol and configuration
Keys and subscription links only come from the service Telegram bot, while configurations themselves are added and switched inside the Happ app. Different configurations can behave differently on certain networks, so it's worth keeping a backup on hand. Adding and switching configurations is explained on the /en/configurations/ page.
Split tunneling: which apps use the VPN
Split tunneling lets you decide which traffic goes through Happ and which goes directly. That's useful when you want local services to bypass the VPN while only selected apps, like a banking client or a work messenger, route through the secure connection, leaving the rest of the device's traffic untouched. Full setup steps are on the /en/split-tunneling/ page.
How these settings interact
Server, configuration, and split tunneling don't work in isolation: an app excluded from the tunnel won't notice a server change, and a configuration can behave differently across servers. It helps to change one setting at a time and check the result rather than flipping everything at once, so you can tell what actually affected speed or stability.
Initial app setup
If you're just getting started with Happ, the complete process — from getting a key in the Telegram bot to the first connection — is on the /en/setup/ page. Once the basics are done, you can fine-tune the server and protocol for your specific needs without starting over.
Frequently asked questions
Where should I start configuring Happ?
Get a subscription key from the service Telegram bot first, then add it to the app — the full steps are on the /en/setup/ page.
How do I know which server to pick?
Look for the lowest latency to your target region in the app's server list.
Why would I need split tunneling?
So some apps or sites bypass the VPN entirely while only the traffic you choose routes through Happ.
Can I keep multiple configurations at once?
Yes, you can add several configurations from the Telegram bot and switch between them without reinstalling.
Connect via the Telegram bot
Open Happ's settings, match the server and protocol to your task, and set up split tunneling in a couple of minutes.
