title: How to consume an API given this information (PHP, Laravel)
body: <p>The API has an internal documentation page that asks me for Client ID, Client Secret, Username and Password.</p>
  
  <p>Once I enter those, it stays "Authenticated" and I can "Try out" any request within that page.</p>
  
  <p>Now the documentation for "Authenticate" is this:</p>
  
  <pre><code>/auth Authenticate to API
  grant_type (password/refresh token)
  client_id*
  client_secret*
  username*
  password*
  token (used only for refresh_token as grant type)
  </code></pre>
  
  <p>When I initiate a POST request (via cURL) I get an access_token.</p>
  
  <p>From then on, what's the correct way to <code>GET</code> an <code>/users</code> endpoint for example and stay authenticated?</p>
  
  <p>I'm doing this from within Laravel 5.8.</p>
