title: Azure Datafactory Web Activity
body: <p>I have developed an Function app and published the same via Azure APIM. I am trying to call the API(APIM) from Data factory Web Activity, which fails with the below. However when I use the Azure function URL + Function key directly in WebActivity this works fine. </p>
  
  <p>So I want to be able to call a REST endpoint internal to my organization from Azure Data Factory using Web Activity. Appreciate any directions on this. </p>
  
  <pre><code>{
      "errorCode": "2108",
      "message": "Error calling the endpoint. Response status code: ",
      "failureType": "UserError
  }
  </code></pre>
