# Customer details

The customer details screen appears when merchants look up a customer during checkout or need to access customer history and profile information. This screen serves as the hub for customer management within POS, displaying customer data, purchase history, and contact details.

### Use cases

* **Loyalty programs:** Display loyalty status, points balance, and tier information.
* **Customer discounts:** Apply personalized discounts based on membership level or purchase history.
* **Profile management:** Launch workflows for updating customer preferences and communication settings.
* **Customer service:** Process loyalty redemptions, account adjustments, and service requests.

## Customer details targets

Use these targets for customer service capabilities, loyalty program integration, or tools for customer engagement and support during transactions.

### Customer details block target

`pos.customer-details.block.render`

Renders a custom information section within the customer details screen. Use this target for displaying supplementary customer data like loyalty status, points balance, or personalized information alongside standard customer details.

Extensions at this target appear as persistent blocks within the customer details interface and support interactive elements that can launch modal workflows using `shopify.action.presentModal()` for more complex customer operations.

### Examples

* ####

  ##### Description

  Add a custom information section to the customer details screen for displaying supplementary customer data. This example shows how to create a block that shows loyalty status, points balance, or personalized information alongside standard customer details.

  ##### jsx

  ```jsx
  import {render} from 'preact';

  export default async () => {
    render(<Extension />, document.body);
  };

  const Extension = () => {
    return (
      <s-pos-block>
        <s-button
          slot="secondary-actions"
          onClick={() => shopify.action.presentModal()}
        >
          Open action
        </s-button>
        <s-text>This is a block extension</s-text>
        <s-text>Customer ID for this customer: {shopify.customer.id}</s-text>
      </s-pos-block>
    );
  };
  ```

### Customer details action (menu item) target

`pos.customer-details.action.menu-item.render`

Renders a single interactive button component as a menu item in the customer details action menu. Use this target for customer-specific operations like applying customer discounts, processing loyalty redemptions, or launching profile update workflows.

Extensions at this target can access the customer identifier through the Customer API to perform customer-specific operations. Menu items typically invoke `shopify.action.presentModal()` to launch the companion [modal](#customer-details-action-modal-) for complete customer workflows.

Examples

### Examples

* ####

  ##### Description

  Build a full-screen modal workflow launched from a customer details action menu item. This example demonstrates creating customer-specific experiences with multi-step processes, forms, and customer data access for operations like loyalty management or profile updates.

  ##### jsx

  ```jsx
  import {render} from 'preact';

  export default async () => {
    render(<Extension />, document.body);
  };

  const Extension = () => {
    return (
      <s-page heading='Customer Details'>
        <s-scroll-box>
          <s-text>Customer ID: {shopify.customer.id}</s-text>
        </s-scroll-box>
      </s-page>
    );
  };
  ```

***

## Best practices

* **Update customer information in real time:** Update displayed customer information immediately when changes are made to reflect the current state, like updated loyalty points, refreshed tier status, and changed preferences.
* **Show clear action confirmations:** Show clear success or error messages that specify which customer was affected. Use messages like "Loyalty points updated for Jane Doe," "Preferences saved successfully," or "Unable to process - customer not found".
* **Ensure service continuity:** Ensure that customer-related changes integrate properly with the overall transaction and customer relationship, like updated customer profile, applied customer discounts, and recorded service interactions.
* **Handle error states gracefully:** Communicate customer data limitations clearly instead of generic error messages. If your extension accesses or modifies customer information, ensure you handle data responsibly, display only necessary information, and provide clear messaging about any data collection, processing, or sharing that occurs through your extension functionality.
* **Write clear and action-oriented labels:** Use action-oriented labels that specify what will happen for this particular customer, with descriptive titles that clearly indicate the information type. Use "Update loyalty tier" or "Loyalty Status" instead of generic labels like "Loyalty options" or "Customer App."
* **Show status and contextual data:** Show current customer status, relevant metrics, and action eligibility to support service decisions, like loyalty tier and points, "VIP customer - expedited service," and recent purchase patterns.

***

## Limitations

* You can only render one [`Button`](https://shopify.dev/docs/api/pos-ui-extensions/2025-10/polaris-web-components/actions/button) component for each POS UI extension using the action (menu item) target.

* Customer data is read-only through the [Customer API](https://shopify.dev/docs/api/pos-ui-extensions/2025-10/target-apis/contextual-apis/customer-api), which provides only the customer ID. To access additional customer information or modify customer data, use external API calls or integrate with the Customer API through your app backend.
