Setting/Changing card due date to not presetted date

[Yonathan Shterenberg]

Hey! I have a card with a due date that I want to be changed to a new due date (that is set on another card) once it's marked complete. I couldn't find any way to do so (except for custom fields, however, it's useful only in the paid version). There is a solution for specific dates (in a day/week or a specific date) but I would like to insert a variable date ({foundcarddate}).

How can I do so?

Hello @Yonathan Shterenberg and @Sergej N. 

The variable you talk of is {foundcardduedate}

However you can't set a due date in standard automation without making that hop with a custom field, requiring Trello standard or premium.

You could do it but using the Trello Rest API but it is an advanced topic.

Oh, that's a shame.. :(

How can I learn about the Rest API?

Thanks for the answer!

I am also interested in the answer to this question. Does anyone have any ideas?
