# `useRequestHeaders`
|
|
|
|
You can use built-in [`useRequestHeaders`](/docs/api/composables/use-request-headers) composable to access the incoming request headers within your pages, components, and plugins.
|
|
|
|
```js
|
|
// Get all request headers
|
|
const headers = useRequestHeaders()
|
|
|
|
// Get only cookie request header
|
|
const headers = useRequestHeaders(['cookie'])
|
|
```
|
|
|
|

|
In the browser, [`useRequestHeaders`](/docs/api/composables/use-request-headers) will return an empty object.

## Example
|
|
|
|
We can use [`useRequestHeaders`](/docs/api/composables/use-request-headers) to access and proxy the initial request's `authorization` header to any future internal requests during SSR.
|
|
|
|
The example below adds the `authorization` request header to an isomorphic `$fetch` call.
|
|
|
|
```vue [pages/some-page.vue]
|
|
<script setup>
|
|
const { data } = await useFetch('/api/confidential', {
|
|
headers: useRequestHeaders(['authorization'])
|
|
})
|
|
</script>
|
|
```
|
|
|
|
::alert{icon=👉}
|
|
[Another example](/docs/getting-started/data-fetching#example-pass-client-headers-to-the-api) shows how we can pass cookies from the initial request to another API route.
