Happ Configurations: Subscription Link vs Single Config
Happ connects using Xray-core configurations built on VLESS over Reality with TLS 1.3 — parameters that tell the app which server to use and how to encrypt traffic while getting around blocks. They're issued only through the service Telegram bot and added to the app in one of two ways: a single subscription link or an individual config. Which one you pick affects how convenient and stable the connection feels.
What a configuration actually contains
A configuration is, at its core, an encrypted bundle of Xray-core parameters: server address, protocol, port, and the keys needed for a secure connection. The Happ app reads this data and builds a tunnel that gets around restrictions on your device. No valid configuration means no connection, so it's worth getting one only from the service Telegram bot rather than from a random link online.
Single config or subscription link
There are two ways to add access to Happ:
- Single config — a fixed set of parameters tied to one specific server, with no automatic updates.
- Subscription link — bundles several servers together and refreshes on its own, so the app doesn't need manual edits to pick up new addresses.
For everyday use, a subscription link is usually the more convenient choice: it needs less manual upkeep and makes it easier to switch servers if one of them stops reaching the sites you need.
Adding a configuration to the app
Keys and links come from the Happ Telegram bot. From there, you copy them into the app, typically by importing the link or scanning a QR code depending on the platform. Step-by-step instructions for Windows, macOS, Linux, Android, iOS, and Smart TV are on /en/setup/.
Where keys are issued and stored
Every key and configuration is tied to your account inside the service Telegram bot, where you can also see which links are active and request new ones. Read more on /en/keys/, and check the general logic of handling configurations in the app on /en/configurations/.
When to switch configurations
If a server slows down or drops the connection, switching to another configuration inside the same subscription link is usually quicker than troubleshooting one fixed config. Browse available servers and picking tips on /en/servers/.
Frequently asked questions
What separates a subscription link from a single config?
A subscription bundles multiple servers and refreshes on its own, while a single config holds fixed parameters for one specific server.
Where do configurations for Happ come from?
Only the Happ service Telegram bot, which issues both keys and subscription links for the app.
Can more than one configuration be active at once?
Yes, Happ can store several links or configs and let you switch between them in the app.
Do configurations need manual updates?
A subscription link usually updates on its own; a single config sometimes needs to be swapped out by hand.
Connect via the Telegram bot
