Trigger Flow in SharePoint 2013 Online with a SharePoint Designer 2013 Workflow HTTP step

Hi everyone.  I need to trigger an HTTP Triggred Flow from a SharePoint 2013 Workflow.  When I use the HTTP action I get back the following error:

 {"error":{"code":"DirectApiAuthorizationRequired","message":"The request must be authenticated only by Shared Access scheme."}}

The Flow triggers if I paste its URL into the webbrowser.  Any ideas?  Thanks!

I wish it worked for us here... I tried everything before finding your article link except for the blank Authorization header (and that did not work Smiley Sad)


I think it's due to my company's proxy settings.


The remote server returned an error:

(407) Proxy Authentication Required.
   at Microsoft.Workflow.Common.AsyncResult.End[TAsyncResult](IAsyncResult result)
   at Microsoft.Activities.Hosting.HostedHttpExtension.HttpRequestWorkItem.OnEndComplete(ScheduledWorkItemContext context, IAsyncResult result)
