title: Where is the associate tag/id for an Amazon account?
body: <p>Here's the info needed for API access:</p>
  
  <pre><code>access_key = &lt;your access key&gt;
  secret_key = &lt;your secret key&gt;
  associate_tag = &lt;your associate id&gt;
  </code></pre>
  
  <p>I know <a href="https://affiliate-program.amazon.com" rel="nofollow">here</a> there is a value ending with <code>-20</code> but I'm not sure if I'm to include the 20 or exclude it? The documentation has no information on this.</p>
