title: Use parametrized values with Azure Logic App
body: <p>I'm working with an Azure LogicApp where the workflow have fixed values. Our DevOps tool is VSTS (Visual Studio Team Services) and because we have multiple environments to handle, I have to do some refactoring (using parametrized values) so in VSTS we'll be able to provide environment-specific values.</p>
  
  <p>Thanks to 2 websites I found on Internet I managed to understand that there are 3 kind of parameters :</p>

  To understand my problem, here's my action :</p>

  I want to have my string "/work/documents" in a parameter value. So in the "Code view" I managed to use a parameter instead of a hard-coded value :</p>
  
  <pre><code>          "triggers": {
          "When_a_file_is_added_or_modified": {
            "type": "ApiConnection",
            "inputs": {
              "host": {
                "connection": {
                  "name": "@parameters('$connections')['sftp_1']['connectionId']"
                }
              },
              "method": "get",
              "path": "/datasets/default/triggers/onupdatedfile",
              "queries": {
                "folderId": "@{parameters('pathToRootFolder')}"
              }
            },
            "recurrence": {
              "frequency": "Hour",
              "interval": 1
            }
          }
        }
  </code></pre>
  
  <p>And in my parameters.json :</p>
  
  <pre><code>    "sftp_1_path_root_folder": {
          "value": "/work/documents"
      }
  </code></pre>
  
  <p>Here's the final result in Visual Studio:</p>

  <p>Am I missing something ? Why isn't the value displayed in the Designer ? Thank you for your help in advance !</p>
