# Location profile (Hydra only)

The SDK supports custom VPN profiles for Hydra-based sessions. This feature allows you to pass specific configuration profiles to control the VPN connection behavior.

* **How to Enable**: Use the `withLocationProfile` method in `SessionConfig.Builder` to apply the desired location profile to the VPN session.
* **Fetching Profiles**: The `LocationProfile` can be fetched dynamically from the backend using the available API.

```kotlin
sdk.getBackend().locations(ConnectionType.HYDRA_TCP, new Callback<AvailableLocations>() {
   @Override
   public void success(@NonNull AvailableLocations availableLocations) {
        //availableLocations.getProfiles()
   }

   @Override
   public void failure(@NonNull VpnException e) {
   }
}); 
```

* **Disabling Location Profile**: To disable a location profile, pass an empty string (`""`) to the `withLocationProfile` method.
