AUTO-FALLBACK
One order. Automatic backup route.
Send the fallback product code (F…), the target, and a maximum price limit (max_price). The system tries the cheapest route first, then switches to an eligible alternative if it fails. You only pay the final successful price.

Auto-Fallback price list
Each product shows its minimum and maximum price along with available variants, so you know the cost range before ordering.
Price limit
The full limit is held upfront from your balance. The final cost never exceeds this limit, and the remainder is returned once the order succeeds.
Automatic refund
If all routes fail, the held balance is fully refunded and a final-status callback is sent to your server.
