The **Update Profile** node lets you modify profile attributes, as well as add or remove tags from profiles. - A profile attribute is a characteristic assigned to profiles. There are two types of profile attributes: custom (those which you create yourself) and default (attributes which are assigned to a profile, such as first name, last name, phone, city, email, and so on). Profiles can have many attributes, all displayed on a card in

**Behavioral Data Hub > Profiles**. - Profile tags help you organize your profiles into groups for better communication and management. To find out more about profile tags, you can refer to [Profile tags](/docs/crm/customer-tag). The actions available in the **Update Profiles** node vary depending on whether the attributes are custom or default.

When the workflow is launched for a large amount of profiles, it can take longer to update the attributes.

## Requirements --- You must implement the tracking code to your website. ## Node configuration --- 1. To configure the settings of the node, click it. **Result**: A pop-up opens. 2. From the **Attribute** dropdown list, you can: - select an existing attribute or tag, - create a new profile attribute or tag by clicking **Add profile attribute** or **Add profile tag**, respectively. 3. From the **Action** dropdown, select an action: - The **Clear field** option removes the old value and leaves the attribute empty. This option is available only for default profile attributes such as `email`. - The **Update** option defines a new value for the profile attribute. - The **Add** option adds the selected tag to a profile. - The **Remove** option deletes the selected tag and/or a custom attribute. 4. For the **Update** option: Next to the action selection dropdown, enter a value that replaces the old value. You can also add [snippets](/docs/assets/snippets) by clicking the

icon in the field. It's useful when you want to update the attribute value with the value of the aggregate, expression or the event parameter. 4. To impose a limit on the action, switch the **Action limit** toggle. Enter a number and from the dropdown list, select the time unit. You can define how many times this action can be executed for the whole automation process (**workflow**), or you can define how many times per second/minute/hour/day/week/month can be executed. 6. Confirm by clicking **Apply**.

If the Update Profile node is used in the workflow triggered by an event occurrence, the changes of attribute are processed in real time. In the case of the workflows triggered by the [Audience node](/docs/automation/triggers/audience-node), the changes of attribute are processed in a separate queue and the duration of the processing depends on the load.

## Example of use ---
