Happ Configurations: Subscription Link vs Single Config
Happ makes its connection through Xray-core configurations based on VLESS over Reality with TLS 1.3 — a set of parameters that tell the app which server to use and how to encrypt traffic while slipping past blocks. They come exclusively through the service Telegram bot and go into the app in one of two forms: a single subscription link or an individual config. Whichever you choose shapes how convenient and stable the connection turns out to be.
What a configuration actually holds
At heart, a configuration is an encrypted set of Xray-core parameters: the server address, protocol, port, and the keys required for a secure connection. Happ reads this data and constructs a tunnel that bypasses restrictions on your device. Without a valid configuration there's no connection, which is why you should obtain one only from the service Telegram bot and never from some random link found online.
Single config versus subscription link
Access can be added to Happ in two ways:
- Single config — a fixed collection of parameters bound to one particular server, with no automatic updates.
- Subscription link — groups several servers together and refreshes itself, 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 demands less manual maintenance and makes switching servers simpler if one of them stops reaching the sites you need.
Adding a configuration to the app
Keys and links are provided 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 is on /en/setup/.
Where keys are issued and kept
Each key and configuration is linked to your account within the service Telegram bot, where you can also view which links are active and request new ones. Find out more on /en/keys/, and review the overall logic of managing configurations in the app on /en/configurations/.
When to change configurations
When a server slows down or drops the connection, moving to a different configuration within the same subscription link is normally faster than troubleshooting one fixed config. Look through the available servers and selection tips on /en/servers/.
Frequently asked questions
What sets a subscription link apart from a single config?
A subscription groups several servers together and updates automatically, whereas a single config carries fixed parameters for one particular server.
Where do Happ configurations come from?
Solely the Happ service Telegram bot, which hands out both keys and subscription links for the app.
Can several configurations be active simultaneously?
Yes — Happ can keep several links or configs and let you switch between them within the app.
Do configurations require manual updating?
A subscription link normally updates by itself; a single config occasionally has to be replaced manually.
