JSON-RPC subscribeToWebhookEvent method is deprecated. Use /3.1/webhook_subscriptions/{topic} instead.

The recommended endpoint for webhooks is /3.1/webhook_subscriptions which is actively maintained and provides access to the newest Cleeng webhook features such as webhook filtering or webhook verification.

The subscribeToWebhookEvent is deprecated as a legacy endpoint and should no longer be used. It's still available for backward compatibility but it's no longer maintained.
