[ARCHIVED] Unable to get Access token using Postman

[dp]

I am unable to get the access token when I post a request using Postman. I am receiving the authorization code from the browser and passing the authorization in the Postman request. I have attached screenshot and I am receiving HTTP status as 400 Bad Request with a message 

{

    "error": "invalid_grant",

    "error_description": "authorization_code not found"

}

Do you have any idea what am I doing wrong here?
