Our Android Drop-in renders MoMo Wallet in your payment form, and redirects the shopper to the MoMo Wallet app or website where they can complete the payment.
Before you begin
This page explains how to add MoMo Wallet to your existing Android Drop-in integration. The Android Drop-in integration works the same way for all payment methods. If you haven't done this integration yet, refer to our Drop-in integration guide.
Before starting your MoMo Wallet integration:
- Make sure you have set up your back end implementation.
- Add MoMo Wallet in your test Customer Area.
Show MoMo Wallet 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 MoMo Wallet 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
.
-
Pass the
paymentComponentData.paymentMethod
to your server. -
From your server, make a /payments request, specifying:
paymentMethod
: ThepaymentComponentData.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 theRedirectComponent.getReturnUrl(context)
.
