A corridor is a (origin, destination, rail) triple. v1 covers two destination corridors; origin is always a USD wallet held by the partner.

​
TH — PromptPay

  • Corridor code: th_promptpay
  • Local rail: PromptPay (Bank of Thailand’s instant payment network)
  • Settlement currency to merchant: THB
  • Refund window: T+7 (payout-partner-side)
PromptPay QR codes are issued by Thai banks to merchants of every size, from airport duty-free counters to street stalls. Zennopay routes the transaction through its licensed payout partner network for the corridor; the partner network handles USD → THB FX and the final push to the merchant’s PromptPay-registered account.

​
VN — VietQR

  • Corridor code: vn_vietqr
  • Local rail: VietQR (interbank QR standard governed by NAPAS)
  • Settlement currency to merchant: VND
  • Refund window: T+1 (payout-partner-side)
VietQR is the unified QR standard across Vietnamese banks. Zennopay’s payout partner for this corridor handles USD → VND conversion and merchant settlement.

​
Choosing a corridor

The corridor is locked when the payment intent is created, and the Zennopay-minted session token is bound to it. Your app picks the corridor based on which country the user is paying in (typically inferred from the QR code itself; partner UX picks the corridor before the user scans).

Roadmap

Additional Southeast Asian corridors are on the roadmap. Contact partners@zennopay.com for current availability.
