# Twilio tool

> Send SMS messages from your agent using your Twilio account.

![Twilio tool cover](/docs/images/tools/integrations/Twilliocover-1.png)

The Twilio tool lets your agent send text messages during a conversation. Use it to send confirmation codes, appointment reminders, order updates, or follow-up information to your users.

This tool sends SMS from a conversation on any channel. To receive texts on a Twilio number and run the conversation over SMS, see [Inbound SMS](/docs/documentation/deploy/sms/inbound). To start a conversation by texting someone first, see [Outbound SMS](/docs/documentation/deploy/sms/outbound).

## Using the Twilio tool

Add the Twilio tool to your agent from **Tools** → **Add tool** → **Twilio**. You can also add tools directly from inside a [Playbook](/docs/documentation/build/steps/playbook) or [Integration step](/docs/documentation/build/steps/integration). Once added, you can call the Twilio tool from inside a [Playbook](/docs/documentation/build/playbooks) or [Workflow](/docs/documentation/build/workflows).
