title: Get AWS SQS queue URL?
body: <p>An AWS SQS queue URL looks like this:</p>
  
  <pre><code>sqs.us-east-1.amazonaws.com/1234567890/default_development
  </code></pre>
  
  <p>And here are the parts broken down:</p>
  
  <pre><code>Always same | Stored in env var | Always same   | ?          | Stored in env var
  sqs         | us-east-1         | amazonaws.com | 1234567890 | default_development
  </code></pre>
  
  <p>So I can reconstruct the queue URL based on things I know except the <code>1234567890</code> part.</p>
  
  <p>What is this number and is there a way, if I have my AWS creds in env vars, to get my hands on it without hard-coding another env var?</p>
