tl;dr Trello will begin requiring API key and token authorization via the Authorization header to access card attachment download URLs. Update: This was previously announced but the implementation has changed enough that we are re-announcing. Query parameter-based authorization will be turned off o…

Can i access to private board/card’s images without login? (I have generated the attachment URL with authorization header, now I want to send image url to another person). Since the user doesn’t have the login, can he access it? Or any other way to send a downloadable link to others? (My board is p…

Do you send the key in the header? The request URL looks good to me. Don’t know if its any different but im using: https://api.trello.com/ instead of https://trello.com/
