4. Retrieve Payment Provider Info from Payment Option Details API.
To receive a payment provider info, refer to the sample payment option detail response below.
Payment Option Detail Parameter
PaymentChannel paymentChannel = paymentOptionDetailResponse.getChannels().stream().filter((channel) -> channel.getContext().getCode().getChannelCode().equalsIgnoreCase("GOOGLEPAY")).findAny().orElse(null);
PaymentProvider paymentProvider = paymentChannel != null ? paymentChannel.getContext().getInfo().getPaymentProvider() : null;
val paymentProvider = paymentOptionDetailResponse.channels.find {
it.context.code.channelCode.equals("GOOGLEPAY", ignoreCase = true)
}?.context?.info?.paymentProvider
Map<String, dynamic>? paymentProvider = paymentOptionDetailResponse['channels'].firstWhere((f) => f['context']?['code']?['channelCode'] == PaymentChannelCode.channel.googlePay, orElse: () => null)?['context']?['info']?['paymentProvider'];
let paymentProvider = paymentOptionDetailResponse?.channels?.find((element: any) => {
return element?.context?.code?.channelCode == 'GOOGLEPAY';
})?.context?.info?.paymentProvider;
5. Construct Google Pay Token Request

if (response.getResponseCode().equalsIgnoreCase(GooglePayPaymentResponseCode.TokenGeneratedSuccess)) {
//Construct google pay payment request.
} else {
//Get error response and display error.
}
}
@Override
public void onFailure(Throwable error) {
//Get error response and display error.
}
});
val paymentProviderRequest = PaymentProviderBuilder(activity).apply {
paymentProvider(paymentProvider)
}.build()
PGWSDKHelper.getInstance().proceedGooglePayPayment(paymentProviderRequest, object : PaymentResultResponseCallback<GooglePayPaymentResultResponse> {

if (response['responseCode'] == GooglePayPaymentResponseCode.tokenGeneratedSuccess) {
//Construct google pay payment request.
} else {
//Get error response and display error
}
}, (error) {
//Get error response and display error
});
await RTNPGW.proceedGooglePayPayment(JSON.stringify(paymentProvider), null, GooglePayAPIEnvironment.production).then(async (response: string) => {
let googlePayPaymentResultResponse = JSON.parse(response);
if (googlePayPaymentResultResponse?.responseCode == GooglePayPaymentResponseCode.tokenGeneratedSuccess) {
