title: Informatica Cloud mapping: load parameters from rest API
body: <p>I'm trying to build a mapping that will load data from one database to another, updating <em>destination</em> with all rows from <em>source</em> that have been created since the most recent row in <em>destination</em>.</p>
  
  <p>The query in <em>Source</em> would be something like this:</p>
  
  <pre><code>SELECT
      *
  FROM table
  WHERE table.creation_date &gt; [[destination max creation_date]]
  </code></pre>
  
  <p>From what I saw in the docs and discussions in the Informatica Cloud communities, the best way to do this would be with a <strong>Parameter</strong>. But from all that I've seen, the only ways to load parameters are:</p>
  
  <ul>
  <li>Hardcode it into the mapping</li>
  <li>Load parameters from a XML file</li>
  </ul>
  
  <p>Is there a way to load parameters from ANYWHERE else? Anything except for a file would be great.</p>
  
  <p>Thanks in advance and sorry for awkward writing.</p>
