# 21602: Message body is required

Log Type: APPLICATION

Log Level: ERROR

## Description

The `Body` OR `MediaURL` parameter is required to send a Message with Twilio.

### Possible causes

You may have attempted to send a message without a `Body` or `MediaURL` parameter.

### Possible solutions

Retry your message including a body or a link to some media. For sample code that shows how to send an SMS message with Twilio's supported helper libraries, cURL, or the Twilio CLI, please see [this short tutorial](/docs/messaging/quickstart)
