# Passing authentication headers to video HTTP requests

Pass custom headers to video HTTP requests with WebViewer Video's service workers. Authenticate videos on the server side for secure access. Learn how with this example. The Apryse Web SDK streamlines

WebViewer Video utilizes [service workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API/) to allow for custom headers to be passed onto HTTP requests that retrieve the video. This gives you the ability to authenticate videos on the server side and access them securely using WebViewer Video. See below example on how to utilize the service worker and pass custom headers.

<pre class="language-js" data-line-numbers><code class="lang-js">import WebViewer from '@pdftron/webviewer';
import { initializeVideoViewer, renderControlsToDOM } from '@pdftron/webviewer-video';

WebViewer({
    path: '/webviewer/lib',
  },
  viewer.current,
).then(async instance => {
  // Extends WebViewer to allow loading HTML5 videos (.mp4, ogg, webm).
  const {
      getVideo,
      loadVideo,
  } = await initializeVideoViewer(
      instance,
      {
        license: '<code class="expression">visitor.claims.wvKey || "YOUR_LICENSE_KEY"</code>',
        `---- Other settings ----`,
      }
  );
  // Load a video at a specific url. Can be a local or public link
  // If local it needs to be relative to lib/ui/index.html.
  // Or at the root. (eg '/video.mp4')
  const videoUrl = 'https://pdftron.s3.amazonaws.com/downloads/pl/video/video.mp4';
  loadVideo(videoUrl, {
    headers: {
      Authorization: 'Bearer testToken',
      TestHeader: 'Test',
    },
  });
});
</code></pre>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/web/video/authentication-headers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
