I am trying to make an automation for our board, but custom fields are not searchable and the proposed hack {{%fieldname}}=value doesnt work (e.g. when going to https://trello.com/search?q={{%fieldname}}=value )
Can there be an easy way in the api to serach/filter cards with a custom field with a certain content.
The only other solution is to search for all cards on the board/list where you expect the card to be and go through each card to find the one you are looking for.
Idealy custom_fields would be a parameter for /search
The API calls https://developer.atlassian.com/cloud/trello/rest/api-group-search/ needed now are:
1 /boards/{id}/customFields/
get the id for the name of the custom field (once)
2 /search
search for all cards on the list/board
3 /cards/{id}/customFieldItems
Loop through each result of step 2 and get the custom field value to compare to the one you are looking for
