I am planning an integration which uses a custom field type (dropdown) and the dropdown should be populated with values I retrieve from a database. The request made to the URL specified in the custom field type is made as soon as the user clicks the field in the recipe. However the request only contains an accountId and an userId. Would be very helpful if it also contains the boardId from the board the automation is about to inserted to. There is a backToUrl field available in the request, but that is empty. If that would contain the URL of the board where the the automation is added to I could extract the boardId from that URL.
Any ideas how to populate a dropdown (custom field type) dynamically based on account Id and boardId?
