# Toast API

* **Error display:** Display error messages and warnings without blocking workflows.
* **Progress updates:** Show progress for long-running operations like data synchronization.

### Properties

The [`shopify` global object](https://shopify.dev/docs/api/pos-ui-extensions/2026-07-rc#target-apis-define-what-your-extension-does) provides methods for showing toast notifications. Access the following properties on `shopify` to display brief, non-intrusive messages to merchants.

* **show**

  **(content: string) => void**

  **required**

  Displays a toast notification with the specified text content. The message appears as a temporary overlay that automatically dismisses after the specified duration. Use for providing immediate user feedback, confirming actions, or communicating status updates without interrupting the user's workflow.

Examples

### Examples

* ####

  ##### Description

  Display a toast notification from a tile. This example demonstrates using \`shopify.toast.show()\` to display a brief, non-intrusive message that automatically disappears. This is useful for confirmations, status updates, or success messages that don't require user interaction.

  ##### jsx

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

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

  const Extension = () => {
    return (
      <s-tile
        heading="My App"
        onClick={() => shopify.toast.show('Toast content', {duration: 5000})}
      />
    );
  };
  ```

***

## Best practices

* **Write clear, concise messages:** Keep content brief since toasts disappear automatically.
* **Provide meaningful feedback:** Use toasts to confirm actions, explain errors, or communicate status changes.
* **Avoid overuse:** Reserve for important feedback. Don't show multiple toasts simultaneously.
* **Handle multiple toast messages:** Multiple toast messages may overlap or interfere with each other if shown in rapid succession. Consider queuing or spacing out notifications appropriately.

***

## Limitations

Toast content is limited to plain text and can't include rich formatting, links, or interactive elements.
