How to Activate a Key in the Happ App
Without a key or subscription link, Happ simply won't reach a server — but activating one in the app takes just a couple of taps.
Key vs. subscription link: what's the difference
A key is a string of parameters that ties the client to your account and the service's servers. A subscription link works similarly but can refresh the server list on its own, with no manual steps needed on your end.
- Both are issued only through the service Telegram bot
- You can't generate a key from inside the Happ app itself — only through the bot
- One key usually works across several of your devices at once
For how to get one, see the Happ Telegram bot article.
Where to find the add-key screen
Happ opens the add-key screen automatically on first launch. If the app is already set up, you can add another key from the main screen.
- Look for a plus-shaped button in the interface — that's usually what handles adding a key or subscription
- Depending on the version, the screen may read "Add configuration" or "Add subscription"
- The steps are identical on Windows, macOS, Linux, Android, iPhone, and Smart TV
Activating the key step by step
The process itself doesn't change from device to device.
- Copy the key or link from the Telegram bot's message
- In Happ, tap the add-key button
- Paste the copied text into the field
- Confirm — the app will pull in the server list

Confirming the key actually worked
Before you try connecting, it's worth checking that the key was accepted.
- At least one entry should appear in the server list
- The number and names of servers depend on your plan
- Connect to any server on the list — a "connected" status confirms everything was added correctly
Key won't add? What to check
Sometimes it doesn't work the first time, and it's almost always the key text itself or its expiration.
- Make sure you copied the whole key, with no stray spaces at either end
- Check whether it's expired — current plans are listed on the Happ pricing page
- If the error keeps happening, request a fresh key from the bot
More causes and fixes are on the Happ not connecting page.
Frequently asked questions

Copy it manually from the Telegram bot and paste it into the app's add-key field.
