# How to Use Dynamic Variables

### Messaging Console <a href="#messaging_console" id="messaging_console"></a>

You can include a dynamic variable in your message while responding to a contact. There are two ways to use dynamic variables:

1. By typing the dollar sign "$"&#x20;

1. By clicking on the variable Icon at the bottom of the Messages Module

Besides contact fields, you can also include a custom field by typing the custom field's name.&#x20;

While composing a snippet's content, you can include a dynamic variable to personalize your quick replies.&#x20;

{% hint style="info" %}
**Tip:** You can have multiple dynamic variables in a single piece of content. Make use of them while composing your messages.
{% endhint %}

{% hint style="warning" %}
**Important:** If the field you are trying to send is empty or the field does not exist at all, the string will not be replaced.
{% endhint %}

### Workflows <a href="#workflows" id="workflows"></a>

Besides trigger variables that are tied to a specific trigger, there are also other variables that can be created and used in the Workflows.&#x20;

1. Save responses from the Contact as variables in the Ask a Question step.&#x20;

2. ​It is also possible to create output variables by adding Form Field in a [Shortcut Form](#workflows). The values of the variables are defined and provided by the User who initiated the Shortcut and filled out the Shortcut form.

3. Then, use the dynamic variables saved in Workflow steps.
