title: How to set Request Headers in Nextjs 9
body: <p>I have been reading the <a href="https://zeit.co/docs/v2/network/headers/" rel="nofollow noreferrer">Headers</a> section on zeit.co to try and work out how to set my <code>authorization: "Bearer ${token}"</code> headers for auth. But I cannot see anywhere in the documentation on how to set custom Request Headers.</p>
  
  <p>My attempt with <code>apollo-link-context</code> does not seem to bare any fruit sadly. Which I thought, its possible <code>nextjs</code> is changing them?</p>
  
  <pre><code>  const authLink = setContext(_ =&gt; {
      return {
        headers: {
          ...headers,
          authorization: `Bearer ${token}`,
        },
      }
  </code></pre>
