How do I filter trigger by attachments?

[David Hall]

Probably a dumb question but I am looking to make a simple trigger for cards that have been moved to a given list that only activates if there is an attachment present (e.g. a Trello Attachment or a Dropbox attachment).

I don't necessarily need to know the name of the attachment, simply check if one is there or not before proceeding with the command.

Is such a thing possible?

As a specific example, I am looking to perform an action to a linked card in the attachments after a card is moved to a specific list, but as it is now, this gets triggered any time any card is moved to that list, regardless of if it has a linked card or not. This is chewing away at my quota of commands run as the command is run, even if there is no actual action being taken.

You can set a label (invisible) when attachment contains https://trello.com and use that label as a condition on the card.

Thanks for this suggestion. Didn't even think of using an invisible label. This was a nice simple workaround that worked for my task.

I don't see the option to check if there's an attachment, but you could do it with a custom field setting it only to the cards with attachments.

You could also assign that custom field automatically
