Returns, for each requested destination country, the entity (legal entity / location) fields that compliance workflows require for a trip there — VAT ID, HR number, registered address and the like. Requiredness is resolved from the processes mapped to that destination and the workflows attached to them, the same source of truth the trip-completeness check uses.

Detecting changes: this endpoint returns a whole snapshot plus a version. Store the version and compare it on your next poll — if it is unchanged, nothing this endpoint reports has changed. There is deliberately no since cursor: the underlying workflow links carry no timestamps and are hard-deleted, so a field that stopped being mandatory would leave no trace in a row-level feed.

Note that entity-field requiredness is configured globally rather than per company, so two companies asking about the same country see the same required set — only company-specific custom fields differ.
