Get All Cards With Specific idCustomField

[Andrew Jackson]

I'm looking to retrieve all cards where a specific custom field is completed.

Looking at cards with the custom field completed, I can see that the idCustomField appears on the api call.  If the card hasn't got the field completed, it doesnt come back on the api call.

I have 500+ cards and only need to return the 10 cards with this customfield.  Looping through the cards errors out due to the number of calls.

Surely there must be a way of getting the cards with this customfield only in 1 call without looping through all cards?

Have you tried using Butler action to collect cards where CF is checked into a checklist then use that checklist to feed into your program via Butler Http Request with payload the cardidlong and may be the checklist name?
