How do I find the Id of a Custom Field in a fairly easy way.

Hi @BrightZebrafish 

API developer ID Helper power-up can help you a lot here...

Hi @BrightZebrafish 

Welcome to the community!

You can get at it through the Trello REST API. You can get it in formulas in the Amazing Fields powerup .  (use "card.idShort" in the formula)

Or  If you want to also retrieve the name of the fields themselves (for example get that "ZIn76ljn-4yeYvz" is actually "priority" in Trello, without needing to hard code it, call the following end point:

boards/{trello board id}/pluginData

This will return an array with the plugins information and in one of the array items, it will include a line along the lines of:

[value] => {"fields":[{"n":"~custom field name~:","t":0,"b":1,"id":"~custom field id that is the weird stuff at the card level~","friendlyType":"Text"}]}

So you just need to figure out the plugin for custom fields in your case, and you can retrieve the key -> value pair for the custom field name and the id associated with it.

It means that if you add / remove fields, or rename them, you can handle it at run time vs changing your code.

This will also give you the options for the custom field (when it is a dropdown like in bdwakefield's example above).
