How to remove all "Mark Complete" checkmarks in cards using Automation

[Luichy Guzman]

I want to be able to schedul an automation either in Butler or through API to remove all NEW completed checkmarks from all the cards in a board.

How could I accomplish that?

Hi @Luichy Guzman !

Through scheduled automations specifically, you won't be able to, as due date actions are only available on regular automation rules, due date rules, and card buttons. 

My recommendation would probably be something like this instead:

Through API you can also do it by making an UPDATE A CARD request and passing the boolean dueComplete as false: https://developer.atlassian.com/cloud/trello/rest/api-group-cards/#api-cards-id-put
