title: Is there a way to use variables within URLs of slack workflows actions?
body: <p>I'm setting up a workflow that takes in a text variable I'd like to use in a later link.</p>
  <p>For example, I ask for &quot;Api Name&quot;, and then want to send a message that <em>both</em> references the api name as well as constructs a url (e.g. <a href="http://swagger.io/docs/%22Api" rel="noreferrer">http://swagger.io/docs/&quot;Api</a> Name&quot;)</p>
  <p>The problem I encounter is the links come up in plaintext if I just try to include that url as plaintext example as above. If I use the editor to try and add a link, the variable is not available.</p>
  <p>My next thought was to try and edit the workflow json to supply some markdown in there, but it looks like the richtext is constructed from a series of elements.
  A link looks like this:</p>
  <pre><code>{
      &quot;type&quot;: &quot;link&quot;,
      &quot;url&quot;: &quot;https://swagger.io/collections/&quot;,
      &quot;text&quot;: &quot;(Link)&quot;
  },
  </code></pre>
  <p>And a token looks like this:</p>
  <pre><code>{
      &quot;type&quot;: &quot;workflowtoken&quot;,
      &quot;id&quot;: &quot;&lt;some uuid&gt;==user&quot;,
      &quot;property&quot;: &quot;&quot;,
      &quot;data_type&quot;: &quot;user&quot;,
      &quot;style&quot;: null
  },
  </code></pre>
  <p>If I merely make the link plaintext and try to append the variable after the prefix I get something like this:</p>
  <pre><code>{
      &quot;type&quot;: &quot;text&quot;,
      &quot;text&quot;: &quot;https://swagger.io/thing/&quot;,
      &quot;style&quot;: {
          &quot;unlink&quot;: true
      }
  },
  {
      &quot;type&quot;: &quot;workflowtoken&quot;,
      &quot;id&quot;: &quot;&lt;uuid&gt;==text&quot;,
      &quot;property&quot;: &quot;&quot;,
      &quot;data_type&quot;: &quot;text&quot;,
      &quot;style&quot;: null
  },
  </code></pre>
  <p>So maybe if we knew all the values <code>&quot;type&quot;</code> could be that would help?</p>
  <p>Not sure where to go from here. Anyone have any suggestions?</p>
