# 21619: A Message Body, Media URL or Content SID is required

Log Type: APPLICATION

Log Level: ERROR

## Description

A Message Body, Media URL or Content SID is required

### Possible causes

You are sending a message using a Messaging Service without specifying a `Body`,`Media URL` or `Content SID`.

### Possible solutions

* Ensure you are specifying the correct API Parameters when sending your message.
* If you are using Content Templates, you need to specify a [Content SID](/docs/content/send-templates-created-with-the-content-template-builder), otherwise you will need to send a ["Body" and/or "Media URL"](/docs/messaging/api/message-resource#create-a-message-resource).
