MOLPay online banking Drop-in integration

Add MOLPay online banking to an existing Drop-in integration.

Our Android Drop-in renders MOLPay online banking in your payment form, and redirects the shopper to their selected bank's website or app to complete the payment.

Before you begin

This page explains how to add MOLPay online banking 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 MOLPay online banking integration:

Make sure that you have set up your back end implementation, and added Drop-in to your payment form.
Add MOLPay online banking in your test Customer Area.

Show MOLPay online banking 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 MOLPay online banking in your payment form, you need to specify in your /paymentMethods request:

countryCode	amount.currency
MY	MYR
TH	THB
VN	VND

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: 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).

    "action": {
        "data": {},
        "method": "GET",
        "paymentData": "Ab02b4c0!BQABAg/H8YU..",
        "paymentMethodType": "molpay_ebanking_fpx_MY",

    }
}

Pass the action object to your client app. Drop-in needs this to redirect the shopper to the issuing bank's app or website.

Check the payment result

Drop-in redirects the shopper to the issuing bank's app or website 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:
- paymentData: The value from the /payments response.
- details: The actionComponentData.details object from Drop-in.
https://docs.adyen.com/payment-methods/molpay/android-drop-in#-payments-details-request
- /payments/details request
{ "{hint:Value from the /payments response}paymentData{/hint}":"Ab02b4c0!BQABAgCJN1wRZuGJmq8dMncmypvknj9s7l5Tj...", "{hint:Value from actionComponentData.details}details{/hint}":{ "payload":"Ab02b4c0!BQABAgCW5sxB4e/==" } }
You receive a response containing:
- resultCode: Use this to present the payment result to your shopper.
- pspReference: Our unique identifier for the transaction.
https://docs.adyen.com/payment-methods/molpay/android-drop-in#-payments-details-response
- /payments/details response
{ "resultCode": "Authorised", "pspReference": "88154795347618C" }

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for MOLPay online banking are:

resultCode	Description	Action to take
Authorised	The payment was successful.	Inform the shopper that the payment has been successful. You will receive the funds in 2-3 days.
Cancelled	The shopper cancelled the payment while on their bank's website.	Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error	There was an error when the payment was being processed.	Inform the shopper that there was an error processing their payment. You'll receive a `refusalReason` in the same response, indicating the cause of the error.
Pending	The shopper has completed the payment but the final result is not yet known. It may take minutes or hours for the MOLPay online banking payments network to confirm this.	Inform the shopper that you've received their order, and are waiting for the payment to be completed. You will receive the final result of the payment in an AUTHORISATION notification.
Refused	The payment was refused by the shopper's bank.	Ask the shopper to try the payment again using a different payment method.

If a shopper completed the payment but failed to return to your website or app, you will receive the outcome of the payment in an AUTHORISATION notification.

Test and go live

To find issuer IDs, make a POST request to /paymentMethods. The issuer IDs are in the details.items array for molpay_ebanking_fxp_MY (Malaysia), molpay_ebanking_TH (Thailand), or molpay_ebanking_VN (Vietnam).
Using any issuer ID that is available for the MOLPay eBanking Component for the respective country, make MOLPay online banking test payments to test the different payment results.

Check the status of the MOLPay test payments in your Customer Area > Transactions > Payments.

Before you can accept live MOLPay payments, you need to submit a request for MOLPay in your live Customer Area.
