Is there a way to make a rule to remove all attachments. (Not links, actual attachments)

[Sam Whitehead]

I'm just looking to have either a rule in place that automatically removes all attachments when a card is added to a list, or even a board button I can use to remove all attachments from cards in a specific list.

I've looked for this before and you get an answer that you can do this with Butler, without any proof that you actually can. I do not see the option to remove all attachments. I see where you can automatically remove a link, but not the actual attachment on the card. (Like a pdf file for instance)

Am I just overlooking something?

Hello @Sam Whitehead 

Simple answer... you can't

You could create an automation that queried Trello's Get Attachments on a Card REST API endpoint and got a list of all the IDs of the attachments on the card, but you'd then have to count the number of IDs returned and make multiple calls the Delete an Attachment on a Card to remove the attachments one by one, which would require the use of a loop, and Trello's out-of-the-box automation doesn't have such looping functionality.

If you Google "Using Trello's automation, can I remove all attachments from a card?" you will get confirmation of the advice I have given to you.

I did some digging and came across this post where someone asked the same question. Hopefully this solution helps you!

I appreciate the response, but unfortunately that will not work. There might be cards with one attachment, there might be some with 6 attachments. Creating a bunch of custom fields on top of the custom fields we already have on our cards that we use (dates, dropdown menus, etc.) would be a huge mess. :(

Yeah, I read through it and wasn't sure if it'd be helpful. The Atlassian team member  who responded on that post mentioned that this was a feature request in their backlog, but didn't provide a link to it. Perhaps you could comment on that post and asking for an update on that request?

@Sam Whitehead , here's an automation rule you can create that you can manually run from a work item to delete all attachments contained on that work item:

@Gary Spross I apologize, I don't know what you mean by work item. That screenshot almost reminds me of Microsoft Workflows? I was talking about creating a rule under the Automation part of Trello.

My bad... I had Jira on the brain.
