Provider ID

ProviderID is a unique identifier that links your subscription to your account on our site. It unlocks advanced app functionality and allows precise tracking of active devices.

How it Works

No more than once per day, the app sends a GET request to:

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

The request includes:

• providerid — your unique identifier

• domain hash of the subscription’s source

• HWID of the device

• operating system name and version

The domain hash guarantees that the ProviderID is bound to the specific subscription domain and prevents it from being used on other sites or in other subscriptions.

Ways to Provide Your ProviderID

You can include the ProviderID in your subscription in three ways:

1. In the URL (query parameter)

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

2. In the subscription body (as a comment)

   #providerid {ProviderID}
   vless://70cc48c5‑b2f4…
   vmess://zkIAU1JitkI…

3. In the HTTP response header

   HTTP/2 200 OK
