# API parameters to configure Desktop Assistant notifications

Parameters of the sendDANotification\(\) method in the `DesktopAppNotificationUtils` script include configure Desktop Assistant notifications.

<table id="table_z5k_bwb_glb"><thead><tr><th>

Parameter

</th><th>

Description

</th></tr></thead><tbody><tr><td>

**notification\_message**

</td><td>

Body text displayed on the notification card. The value must be a non-empty string and not exceed 1000 characters. If this condition is not met, the API returns a 400 error.

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

**notification\_title**

</td><td>

Title text displayed at the top of the Desktop Assistant notification card. If omitted, the notification card displays an empty title without raising an error.

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

**recipient\_list**

</td><td>

The `sys_id` values of the intended recipients, sourced from the User \[sys\_user\] table and provided as a comma-separated string.

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

**referrer\_id**

</td><td>

The sys\_id of the record that the notification links to.

 This parameter works in combination with **referrer\_table**. If only one of these two parameters is provided, the link behavior is unpredictable.

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

**referrer\_table**

</td><td>

The name of the table containing the record that the notification links to. For example, incident or sc\_request.

 This parameter works in combination with **referrer\_id**. If only one of these two parameters is provided, the link behavior is unpredictable.

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

**source**

</td><td>

The source application that triggered the notification. Accepted values are **mim** \(Major Incident Management\) and **pe** \(Proactive Engagement\). The value is case-insensitive. Any other value causes the API to return a 400 error.

**Note:** Desktop Assistant sends notifications for a new source only if the source is added as a choice value in the **Notification source** field of the Desktop Assistant notification \[sn\_dex\_desktop\_assistant\_notification\] table. This enables Desktop Assistant to recognize and track the source.
