# Update custom fields thinklet

The **Update custom fields** thinklet writes values to existing manual custom fields—**Device** or **User** object. Refer to [Custom fields management](/platform/user-guide/administration/content-management/custom-fields-management.md) to learn how to create and configure manual custom fields.

Use this thinklet to store values in custom fields from workflow executions, as the result of a decision or a user response, for downstream use and automations:

* Update metadata such as compliance, onboarding, or asset tracking.
* Update Nexthink dashboards or investigations.
* Trigger follow-up workflows based on updated custom field values.

{% hint style="info" %}
Refer to [Creating workflows](/platform/user-guide/workflows/creating-workflows.md#updating-custom-fields-in-workflows-for-downstream-use) for use case examples of **Update custom fields** thinklets.

## Configuring the Update custom fields thinklet

Fill in the following configuration fields:

<div align="left"><figure><img src="/files/xp9nsERWtWYhaO9vNgRl" alt="" width="361"><figcaption></figcaption></figure></div>

* **Name**: Enter a unique name for the thinklet.
* **ID**: Auto-generated based on the name.
* **Description (optional)**: Describe the thinklet purpose to facilitate collaboration.
* **Object**: Select either **Device** or **User**. The object defines which custom fields are available.
  * To update both **Device** and **User** objects, chain multiple thinklets.
* **Select custom field**: Choose one or more manual custom fields (up to 10) to update. Choose how to assign the value:
  * **Custom value**: Enter a fixed value.
  * **Device** or **User** properties, such as **CPU** or **Entity**.
  * **Thinklet**: Use output from a previous thinklet. For example, a campaign response.

{% hint style="warning" %}
Custom field updates are asynchronous and may take up to 5 minutes. If later workflow steps need to read the updated values, add a **Wait** thinklet.

You can update up to 10 custom fields per thinklet for a specific object. Check the status of the update result from the [workflow execution timeline](/platform/user-guide/workflows/monitoring-workflows-dashboard/troubleshooting-workflows.md#update-custom-fields).
