View A DM media via URL


Hi, I have URL media (photo) link from a DM message we retrieve earlier. Our agent will need to view the photo at later time but we don’t want to give them the Twitter login info. According to document, there is another way to view the media file as “by signing a request with the user’s access token using OAuth 1.0A”. I am wondering how to sing the request using the access token, Does nay one know how to form the URL using the access token? Thanks, Tom.


Can anyone help me here? What is the easily way to view a DM photo via URL when I have access token. Thanks.
