How to automatically remove attachments

Katerina Bohacova

Hi, I am creating various rules to adjust my board. I have managed to automatically remove due dates and labels. However, I have not managed to create a rule automatically removing attachments. It is not an available option in the "add/remove" section of a new rule, or anywhere else. Can you please help me find it?

Thanks a lot, Katerina

Hi Katerina! Welcome to the community!

I did some testing in here, but I couldn't find a way to directly remove an attachment like for labels and due dates. There's a way to use the attachment link.

So I tested an alternative that might help in your case. For that, I had to create 2 rules and use a custom field (available in Premium). Here it goes: 

1 - Create a rule that when an attachment is added to a card, fill out the custom field with the attachment link. For that, I used the variable -> {attachmentlink}

when an attachment is added to a card, set custom field "Attachment link" to "{attachmentlink}"

2 - Create a rule with a trigger (in this case I used a label to trigger an action) that will look for the attachment link in the custom field and remove the attachment from the card. Here used the variable {{%Custom Field name}}

when the blue label is added to a card, remove link "{{%Attachment link}}"

The downside is that if you usually attach more than one doc to a card, it will be necessary to create more custom fields for each attachment. 

Here is some additional documentation that might help:

Hope that helps!
