Napas card Drop-in integration

Our Android Drop-in renders Napas card in your payment form, and redirects the shopper to the Napas card app or website where they can complete the payment.

Requirements

Show Napas card in your payment form

Drop-in uses the countryCode and the amount.currency from your /paymentMethods request to show the available payment methods to your shopper.

To show Napas card in your payment form, specify in your /paymentMethods request:

• countryCode: VN
• amount.currency: VND
• amount.value: The value of the payment.

Make a payment

When the shopper proceeds to pay, Drop-in returns the paymentComponentData.paymentMethod.

1. Pass the paymentComponentData.paymentMethod to your server.

2. From your server, make a /payments request, specifying:

   • paymentMethod: The paymentComponentData.paymentMethod from your client app.
   • returnUrl: URL to where the shopper should be redirected back to after they complete the payment. Get this URL from the Component in the RedirectComponent.getReturnUrl(context).

In the  /payments response, note the `action` object. This contains the information needed to redirect the shopper.

<div data-component-wrapper="code-sample">
<code-sample
    :title="'/payments response'"
    :id="''"
    :code-data="[{&quot;language&quot;:&quot;json&quot;,&quot;tabTitle&quot;:&quot;&quot;,&quot;content&quot;:&quot;{\n   \&quot;resultCode\&quot;:\&quot;RedirectShopper\&quot;,\n   \&quot;action\&quot;:{\n      \&quot;paymentMethodType\&quot;:\&quot;momo_atm\&quot;,\n      \&quot;method\&quot;:\&quot;GET\&quot;,\n      \&quot;url\&quot;:\&quot;https:\/\/checkoutshopper-test.adyen.com\/checkoutshopper\/checkoutPaymentRedirect?redirectData=...\&quot;,\n      \&quot;type\&quot;:\&quot;redirect\&quot;\n   }\n}&quot;}]"
    :enable-copy-link-to-code-block="true"
    :code-sample-card-size="'fullsize'"
></code-sample>

If your integration is set up correctly, the action object is passed from your server to the client.

Check the payment result

Drop-in redirects the shopper to complete the payment. When the shopper returns back to your app, Drop-in provides the actionComponentData object.

From your server, make a POST /payments/details request providing:

• details: The actionComponentData.details object from Drop-in.

You receive a response containing:

• resultCode: Use this to present the payment result to your shopper.
• pspReference: Our unique identifier for the transaction.
