title: REST API calls through Pentaho Data Integration (Spoon)
body: <p>Hello Pentaho Experts,</p>
  <p>I am attempting to make a REST API call through REST Client in Pentaho. I have a Api key for authentication. I tried it in Postman, and it works perfectly fine, but Pentaho throws 403 status code. Below is the postman screenshot:</p>

  <p>My Pentaho transformation contains two steps. I am passing URL through &quot;Generate Rows&quot; step and then adding Key and Value in the Header:</p>
