Napas is the domestic card network in Vietnam. Customers pay with a debit card issued by a Vietnamese bank and confirm each payment with their bank. Payrails processes Napas through dLocal as the payment service provider (PSP). Open the dLocal guide below for its setup steps and request examples.

​
How a Napas payment works

Napas is a redirect payment method:
  1. The customer selects Napas at checkout.
  2. Payrails returns a redirect URL from dLocal, and the customer goes to a hosted payment page.
  3. The customer enters their Napas card details and confirms the payment with their bank.
  4. dLocal sends the customer back to your returnInfo URL.
  5. Payrails receives the final result from dLocal and updates the payment.
Each payment is single-use: the customer confirms every payment on its own. Payrails captures Napas payments immediately, so a successful payment is final. To return funds, refund the payment.

​
Supported currencies and countries

Napas supports VND (Vietnamese dong) as its only presentment currency.

​
Integrate Napas

The dLocal guide covers the setup in dLocal and in Payrails, plus the request fields dLocal requires.

Check PSPs

Each Napas payment is a new customer-initiated payment.

Ways to integrate Napas

  • Payrails SDK: the Web SDK shows Napas when your workflow returns it as a payment option, and redirects the customer to the hosted payment page. To control how the redirect opens, listen for the actionRequired event.
  • Payrails API: call lookup payment options, then authorize with napas as the paymentMethodCode. The dLocal guide lists the meta fields dLocal requires.
In both cases, confirm the final result through webhook notifications or the execution status. Don’t treat the customer’s return to your success URL as proof of payment.
