Migrate to Polaris

Version 2025-07 is the last API version to support React-based UI components. Later versions use web components, native UI elements with built-in accessibility, better performance, and consistent styling with Shopify's design system. Check out the migration guide to upgrade your extension.

Examples

import React from 'react';

import {

Text,

Screen,

ScrollView,

Navigator,

reactExtension,

useApi,

} from '@shopify/ui-extensions-react/point-of-sale';

const Modal = () => {

const api = useApi<'pos.product-details.action.render'>();

return (

<Text>{`Product ID: ${api.product.id}`}</Text>

</ScrollView>

</Screen>

</Navigator>

);

};

export default reactExtension('pos.product-details.action.render', () => (

));

Get the current product ID

Description

Retrieve the unique identifier of the product currently associated with the extension's context. This example shows how to access the product ID from product detail screens, enabling you to fetch additional product data, implement custom actions, or integrate with inventory and pricing systems.

React

import React from 'react';

import {
  Text,
  Screen,
  ScrollView,
  Navigator,
  reactExtension,
  useApi,
} from '@shopify/ui-extensions-react/point-of-sale';

const Modal = () => {
  const api = useApi<'pos.product-details.action.render'>();
  return (
    <Navigator>
      <Screen name="ProductApi" title="Product Api">
        <ScrollView>
          <Text>{`Product ID: ${api.product.id}`}</Text>
        </ScrollView>
      </Screen>
    </Navigator>
  );
};

export default reactExtension('pos.product-details.action.render', () => (
  <Modal />
));

TS

import {
  Navigator,
  Screen,
  ScrollView,
  Text,
  extension,
} from '@shopify/ui-extensions/point-of-sale';

export default extension('pos.product-details.action.render', (root, api) => {
  const navigator = root.createComponent(Navigator);
  const screen = root.createComponent(Screen, {
    name: 'ProductApi',
    title: 'Product Api',
  });
  const scrollView = root.createComponent(ScrollView);
  const text = root.createComponent(Text);

  text.append(`Product ID: ${api.product.id}`);
  scrollView.append(text);
  screen.append(scrollView);
  navigator.append(screen);
  root.append(navigator);
});

Anchor to Best practicesBest practices

Implement variant-specific features: Use the variant ID to enable specialized functionality like variant-specific pricing, inventory checks, or cart operations.
Validate product access: Verify that the product ID and variant ID are valid before performing product-specific operations or external API calls.

Anchor to LimitationsLimitations

The API provides only basic product identifiers—use Shopify APIs or external systems to fetch additional product details like title, description, pricing, or inventory levels.
Product data reflects the current POS session and may not include real-time updates from other channels until the session is refreshed.
