# Support

The Support API allows you to optionally register a custom handler when support requests are made directly through App Bridge. This interaction is triggered when a merchant clicks the get support button at the top of the app.

**Tip:** To register a custom support callback, you must define a \<a href="/docs/apps/launch/distribution/support-your-customers#custom-support-events">Support link extension\</a> and the link extension must point to a page within your app. This is to ensure consistent behavior when a merchant clicks a support button outside of the app. Without a support link extension, the support callback will be ignored.

## Support

The Support API provides a registerHandler method that registers a handler to call when support is requested. It allows you to provide bespoke, in-app support such as opening a live chat widget.

* **registerHandler**

  **(callback: SupportCallback) => Promise\<void>**

### SupportCallback



void | Promise\<void>

```ts
void | Promise<void>
```

```ts
() => void | Promise<void>
```

Examples

### Examples

* #### Register support handle

  ##### Default

  ```js
  // Define the callback function
  const handler = () => {
    // implement your custom functionality
    openLiveChat();
  };

  // Register the callback
  shopify.support.registerHandler(handler);
  ```
