PaymentMethodPresent Always False

by ADMIN 34 views

Introduction

Google Pay provides a seamless payment experience for users, allowing them to make transactions with ease. However, when using the existingPaymentMethodRequired parameter in the IsReadyToPayRequest, the paymentMethodPresent field is always set to false, even when a matching card is present in the user's Google account. This article aims to investigate this issue and provide a solution.

Describe the Bug

When using existingPaymentMethodRequired = true in IsReadyToPayRequest, the returned paymentMethodPresent is always false even though I have a card in my Google account which matches the allowedPaymentMethods.

To Reproduce

To reproduce this behavior, follow these steps:

Step 1: Create a Payments Client

const paymentsClient = new google.payments.api.PaymentsClient({ environment: 'PRODUCTION' });

Step 2: Define the IsReadyToPayRequest

const isReadyToPayRequest = {
    "apiVersion": 2,
    "apiVersionMinor": 0,
    "allowedPaymentMethods": [
        {
            "type": "CARD",
            "parameters": {
                "allowedCardNetworks": [
                    "MASTERCARD",
                    "VISA",
                    "AMEX",
                    "DISCOVER"
                ],
                "allowedAuthMethods": [
                    "PAN_ONLY",
                    "CRYPTOGRAM_3DS"
                ]
            }
        }
    ],
    "existingPaymentMethodRequired": true
};

Step 3: Call the isReadyToPay Method

const isReadyToPay = await paymentsClient.isReadyToPay(isReadyToPayRequest); // { "result": true, "paymentMethodPresent": false }

Expected Behavior

paymentMethodPresent should be true.
