title: Unsubscribe link in email redirect to Vue.js landingpage
body: <p>I'm working on the frontend for a Vuejs app with a PHP/Laravel backend. I have no PHP/Laravel or backend know-how.</p>
  <p>I have to create a landingpage for clients to unsubscribe for after clicking the unsubscribe link.</p>
  <ul>
  <li>We have multiple newsletters.</li>
  <li>Unsubscribe link redirects to a Vuejs landingpage.</li>
  <li>User can then unsubscribe for some or all newsletter updates.</li>
  </ul>
  <p>The problem now is:</p>
  <p>I can't show them all the newsletters they're subscribed for without first having to login. We don't want them to log in.</p>
  <ul>
  <li>What data do I need from the backend to show the client all the newsletters they're subscribed for?</li>
  <li>How is this data implemented in the newsletter and or unsubscribe link?</li>
  <li>And how can I catch that data on the Vuejs frontend when they're redirected to the landingpage?</li>
  </ul>
  <p>When they're are logged in, I make an api call to get a contactDetails object which has all the newsletters they're subsribed for. I then simply toggle that data when they unsubscribe and make a post request to update the contactDetails.</p>
  <p>When they're not logged in, it obvioustly throws a 401 unauthorized error when fetching the contactDetails.</p>
  <p>What's the best way to get this to work?</p>
  <p>Frontend: Vuejs
  Backend: Laravel</p>
