WAHA 2025.12 - Custom Device Names, Calls Automation

🏷️ Custom Device Name

You can now label a session so it shows up with a friendly name under WhatsApp → Linked Devices. Configure the deviceName once and keep your fleet easy to identify.

See the full setup flow in 🖥️ Sessions – Device name. Custom names apply to the QR flow, so keep pairing codes reserved for default names.

📞 Calls App – Auto Reject + Auto Reply

Enable the built-in 📞 Calls App to automatically reject incoming calls and reply with a clear message that guides users to text or voice.

🧪 Calls API – Reject Programmatically

If you want full control, the Calls API lets you reject calls on demand. Use the call.received event to grab the IDs, then respond with:

POST /api/{session}/calls/reject

Details and events are in 📞 Calls.
