How to sync Trello Custom Fields

Note: The ability to sync custom fields is only available for certain plans

Ever wish you could sync the data in your Trello Custom Fields across different boards in Trello, or even into different tools like Asana, Jira, or Wrike? Due to some recent changes in Trello's Custom Fields API, this is now possible, and it's very simple to do with Unito! Let's have a look at how it's done.

Getting started with Custom Fields

If you've never used Trello custom fields before, it's very simple to do. All you need to do is add Trello's power-up called "Custom Fields" from the power-up menu, and you're all set! 

Once you've added that, you'll notice that all of your cards will now have a 'Custom Fields' option on the right-hand side. From here, you can add in as many custom fields as you'd like to whichever card you'd like. In this example below, I've added a date field called 'Start Date', and a number field called 'Number of requests'. You can add as many of these as you'd like to as many cards as you'd like. And that's Trello Custom Fields!

Syncing Trello Custom Fields to other tools

Once you've got your Custom Fields set up in Trello, hooking them up to another set of custom fields in another tool (or Trello itself!) is very simple. Set up your sync, just as you normally would, then edit the sync and head over to the "Map Fields" tab. From there, select the drop-down menu on the Trello side of your sync, and choose the custom field of your choice. Next, select the other side's drop-down menu, and you'll be able to select any custom field of a matching type (or, failing that, the description footer). 

In this example, I've used the same Trello board with the "Number of Requests" field and the "Start Date" field, and I'm mapping them to my Asana project. I've created a custom field in Asana called "Number of reports", which I've mapped to "Number of Requests", and I'm about to map the Start date here to the Description footer in Asana. Note that I could map it to the due-date if I wanted, but since it's already mapped, I'll just put it in the Description footer.
