title: Shopify REST API Authorization Credentials won't work
body: <p>i'm pretty desperate right now. I'm trying to send GET request to my <code>shopify</code> shop and the authorization (Basic Auth) of the request is not working:</p>
  <pre><code>(&quot;errors&quot;: &quot;[API] Invalid API key or access token (unrecognized login or wrong password)&quot;). 
  </code></pre>
  <p>I just don't get it, which username and password do i have to use? Are the App Credentials (<code>API key</code>, <code>API secret key</code>) not right? If not, what's the right password and how do i get it?</p>
  <p>Thanks in advance!</p>
