How to remove/delete a due date from a card using Trello API, I am unable to find it on trello API. Is it possible? If it’s not, Is there any workaround? Thanks!
You can update any field on a card, including the due date, via a PUT to
1/cards. You will see in the parameters that
due is an option.
For future questions on “how to do X with the API”, I’d highly recommend opening up your browser’s network tab and watching what requests the Trello web client makes to do the thing you are trying to do. Generally, the web client makes the exact same request that you are trying to make.
