# Send Message

**Who should read this article**: Administrators

Send messages to callers over text channels, such as SMS and WhatsApp.

## Introduction

Use the **Send Message** node to send a text message to a caller. Send a message to deflect callers from IVR to text channels.

              Important

              

The call continues to the next node regardless of the outcome of the message execution (sent, not sent, delivered, not delivered, or error).

When the message is sent, an interaction is logged to the [CDR](/v1/docs/reporting-cdr).

### Connections

The **Send Message** node allows unlimited input connections and 1 output connection.

## Using the Send Message node

To add a **Send Message** node to your workflow, click the **Send Message** node icon:

To make an input connection, drag a link to the **Send Message** node from any node supporting an output connection. To make an output connection, drag a link from the **Send Message** node to any node supporting an input connection.
