# FetchGetUrlFunc

```ts theme={null}
type FetchGetUrlFunc: (req, signal?) => Promise<GetUrlResponse>;
```

Used to perform a fetch; use this to override the underlying network fetch layer. In NodeJS, the default uses the
"http" and "https" libraries and in the browser `fetch` is used. If you wish to use Axios, this is how you would
register it.

## Parameters

| Parameter | Type                                                |
| :-------- | :-------------------------------------------------- |
| `req`     | [`FetchRequest`](/sdk/content/classes/FetchRequest) |
| `signal`? | `FetchCancelSignal`                                 |

## Returns

`Promise`\<[`GetUrlResponse`](/sdk/content/type-aliases/GetUrlResponse)>
