Custom fields
Delete a custom field
Deletes a field definition - only when nothing references it (usage_count must be 0, otherwise 409 custom_field_in_use; detach it from every card’s form_builder first). Scope: custom_fields:write.
What happens to data:
- Stored customer values under this key are PRESERVED on the customer records (history) but stop validating and stop rendering
- The
keybecomes available again; re-creating it with a DIFFERENT type is allowed - old stored values simply fail validation on their next write (no silent coercion)
