# Twilio API

## Overview

Connect your ElevenLabs AI agents with Twilio to send SMS and MMS messages, and look up message and call history. This integration enables your agents to communicate with customers via text during or after a conversation, and retrieve previous interaction records for context.

## Capabilities

| Capability                | Support                                                                                                                |

| Zero retention mode (ZRM) | Not supported                                                                                                          |
