Status values
complianceStatus is a three-state rollup:
decision is populated after the terminal status is reached:
VALID_EXPORT— VAT-exempt transaction complete.VAT_APPLICABLE— VAT must be applied on the final invoice.
Blockers
blockers[] is the actionable list of what’s missing. Each entry carries:
module— which module is blockingcode— machine-readable key (safe to map to UI copy)message— human-readable explanation
Per-VIN variance
Transport state may differ per VIN in multi-VIN orders (one vehicle picked up, another pending). Checkmodules.transport.vins[] for per-VIN
milestones. Buyer/invoice/payment are order-level.
Polling efficiently with ETag
The rollup supportsIf-None-Match for cheap polling:
version bumps. Use a short poll interval
(10–60s) for orders in flight; less for completed orders.
