Happ Configurations: Subscription Link vs Single Config
Happ establishes connections using Xray-core configurations based on VLESS over Reality with TLS 1.3 — parameters that tell the app which server to use and how to encrypt traffic while slipping past blocks. They come solely from the service Telegram bot and are added to the app in one of two forms: a single subscription link or an individual config. The one you choose shapes how convenient and stable the connection turns out to be.
What a configuration really holds
At heart, a configuration is an encrypted package of Xray-core parameters: the server address, the protocol, the port, and the keys required for a secure connection. Happ reads that data and constructs a tunnel that routes around restrictions on your device. Without a valid configuration there's no connection, which is why it's worth obtaining one strictly from the service Telegram bot rather than some random link found online.
Single config or subscription link
Happ gives you two ways to add access:
- Single config — a fixed set of parameters bound to one particular server, with no automatic updates.
- Subscription link — groups several servers into one and refreshes on its own, so the app doesn't need manual edits to pull in new addresses.
For day-to-day use, a subscription link is generally the handier option: it calls for less manual upkeep and makes it simpler to change servers if one of them stops reaching the sites you're after.
Adding a configuration to the app
Keys and links are issued by the Happ Telegram bot. From there you transfer them into the app, usually by importing the link or scanning a QR code, depending on the platform. Step-by-step guidance for Windows, macOS, Linux, Android, iOS, and Smart TV lives at /en/setup/.
Where keys are issued and kept
Each key and configuration is linked to your account inside the service Telegram bot, where you can also view which links are active and request new ones. There's more on /en/keys/, and you can look over the general approach to handling configurations in the app at /en/configurations/.
When to change configurations
When a server slows down or drops the connection, moving to another configuration inside the same subscription link is typically faster than troubleshooting one fixed config. Look over the available servers and picking tips at /en/servers/.
Frequently asked questions
What separates a subscription link from a single config?
A subscription groups several servers together and updates by itself, whereas a single config carries fixed parameters for one particular server.
Where do configurations for Happ come from?
From the Happ service Telegram bot alone, which hands out both keys and subscription links for the app.
Can more than one configuration be active at once?
Yes — Happ can keep several links or configs and let you switch between them within the app.
Do configurations need manual updates?
A subscription link generally refreshes itself; a single config now and then has to be replaced by hand.
Connect via the Telegram bot
Pick up a subscription link from the Happ Telegram bot and connect it in the app by following the setup guide.
