You can use the built-in [`useRequestHeader`](/docs/api/composables/use-request-header) composable to access any incoming request header within your pages, components, and plugins.
```ts
// Get the authorization request header
const authorization = useRequestHeader('authorization')
```
::tip
In the browser, `useRequestHeader` will return `undefined`.
::
## Example
We can use `useRequestHeader` to easily figure out if a user is authorized or not.
The example below reads the `authorization` request header to find out if a person can access a restricted resource.
```ts [middleware/authorized-only.ts]
export default defineNuxtRouteMiddleware((to, from) => {
if (!useRequestHeader('authorization')) {
return navigateTo('/not-authorized')
}
})
```
