# Notification variables

Use notification variables to display dynamic information in the body of a notification such as a field value, a link to a record, or a link to system preferences.

## Syntax

Specify a notification variable using this syntax:

```
${variable-name+variable-parameters}
```

The **variable-name** portion is always required. Not all notification variables support the variable-parameters portion. When available, most variable parameters are optional. See the list of available notification variables for variable names and available parameters.

## Available variables

The system provides these notification variables.

<table id="table_ojr_mjc_ww"><thead><tr><th>

$\{`field-name`\}

$\{`image-field-name`\}

-   $\{URI\}
-   $\{URI\_REF\}

</td><td>

Display a link to the current record.-   **URI**: The link text is the word `LINK`.
-   **URI\_REF**: The link text is the display value of the record.

 **Note:** These variables don't apply to records in Workspace. To link to a record in Workspace, create a mail script that prints a URL to a notification. For more information, see [Linking to a record in Workspace](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/c_EnablingLinksToServiceNowRecords.md).

</td><td>

Any valid **sysparm** URL parameter. For example:-   sysparm\_scriptlet
-   sysparm\_view

</td></tr><tr><td>

-   $\{`reference-field`.URI\}
-   $\{`reference-field`.URI\_REF\}

</td><td>

Display a link to the record listed in a reference field.-   **URI**: The link text is the word `LINK`
-   **URI\_REF**: The link text is the display value of the record.

</td><td>

Any valid **sysparm** URL parameter. For example:-   sysparm\_scriptlet
-   sysparm\_view

</td><td>

Display a link to the specified record within a CMS page.

**&lt;CMS-site&gt;/&lt;CMS-page&gt;**: The required relative path to the CMS page.

</td></tr><tr><td>
