title: Composer PHP version issue
body: <p>I'm trying to integrate Flagship API into a website. It uses composer for this, and I've never used it before. I figured out how to install it using Putty, and I tried running the command to install the API</p>
  
  <pre><code>composer require flagshipcompany/flagship-rest-client
  </code></pre>
  
  <p>This is the error I receive:</p>
  
  <blockquote>
    <p>[InvalidArgumentException]
      Package flagshipcompany/flagship-rest-client at version  has a PHP requirem
      ent incompatible with your PHP version (5.6.30)</p>
  </blockquote>
  
  <p>I've tried several things to change the PHP version the shell is using, including finding the files with the php version 7.1.14 and changing the paths in bash files. When I run </p>
  
  <pre><code>php -v
  </code></pre>
  
  <p>It returns </p>

  <p>Not really sure what the issue here is. I've tried changing the php version in CPanel as well, and no luck. </p>
