### Add channel to app

1. Select *Configuration* tab of your application&#x20;
2. Choose *+ Add channel* under *Delivery* section > Choose *WhatsApp via Twilio*
3. Choose your Twilio workspace integration from the *Integration* dropdown
4. Enter *Phone number*
5. Click *Create channel*
6. Click *Save*

{% hint style="info" %}
*Phone number* is unique to the *WhatsApp via Twilio* channel and will need to be copied over from Twilio manually. When you build and deploy your application, NLX ensures that Twilio routes traffic from the assigned phone number to your deployed application.
