# Twilio

Before configuring your own phone number, you can configure Twilio Sandbox environment to test your chatbot directly on WhatsApp as follows:

* Create your chatbot and, when ready to publish, open the WhatsApp channel settings
* Select Twilio as provider
* Create a standard [Twilio ](https://www.twilio.com)account. It is fully free as long as you are using the sandbox
* Go to the [Twilio Sandbox for WhatsApp](https://www.twilio.com/console/sms/whatsapp/sandbox) page
* Copy the Xenioo hook url from the publish page
