Provider ID

Provider ID is a unique identifier that links your subscription to an account on the website happ-proxy.com. It provides access to advanced application usage statistics and allows accurate tracking of the number of active devices.

Where to Get Provider ID?

To obtain the Provider ID, you need to register on the website https://happ-proxy.com

After registration, you will be able to see it in the upper right part of the screen or in the user profile.

How It Works

Once a day, the application sends a GET request to:

https://check.happ-proxy.com/provider?id={ProviderID}

The request includes:

• providerid — your unique identifier;

• domain hash, from which the subscription is loaded;

• HWID of the device;

• name and version of the operating system.

The domain hash ensures that the ProviderID is tied to a specific subscription domain and prevents its use on other sites or in third-party subscriptions.

Ways to Transmit ProviderID

You can add ProviderID to the subscription in three ways:

1. In URL (query parameter)

   https://your-domain.com/sub/123#?providerid={ProviderID}

2. In the Subscription Body (comment)

   #providerid {ProviderID}
   vless://70cc48c5‑b2f4…
