Getting "Workflow Instance Token is invalid" error from postman

Hi,

    I'm trying to make a call to "Component workflow", using Postman. I'm using all the information provided on API endpoints page. The token is recently generated and is part of URL in the call, still I'm getting " Workflow Instance Token is invalid." message. Is there some setting I need to do in Nintex for postman to call? I'm using the trial version. Here is the screen shot.Thanks
