Usage

Basic Import

import Bill24Sdk from 'react-native-bill24-sdk';
import { 
  Bill24InstantPaymentProps, 
  Bill24InstantPaymentTopUpProps 
} from 'react-native-bill24-sdk';

Instant Payment

Use this method to initiate a general instant payment:

const handleInstantPayment = async () => {
  try {
    const result = await Bill24Sdk.instantPaymentSdk({
      userSyncCode: "your-user-sync-code",
      refererKey: "your-referer-key", 
      language: "en", // "en" | "km"
      isDarkMode: false,
      isProduction: false, // Set to true for production
      testingEnv: "DEMO" // "STAG" | "PRODUCTION" | "PILOT" | "DEMO"
    });

    if (result.success) {
      console.log('Payment successful:', result.message);
    } else {
      console.log('Payment failed:', result.message);
    }
  } catch (error) {
    console.error('Payment error:', error);
  }
};

Top-up Payment

Use this method for wallet top-up payments:

const handleTopUpPayment = async () => {
  try {
    const result = await Bill24Sdk.instantPaymentSdkTopUp({
      paymentMethodId: "payment-method-id", // Bill24 wallet ID
      refererKey: "your-referer-key",
      language: "en", // "en" | "km"
      isDarkMode: false,
      isProduction: false, // Set to true for production
      testingEnv: "DEMO", // Ignored if isProduction is true
      isDisplayCurrencySymbol: true // Display ៛1,000 vs KHR 1000
    });

    if (result.success) {
      console.log('Top-up successful:', result.message);
    } else {
      console.log('Top-up failed:', result.message);
    }
  } catch (error) {
    console.error('Top-up error:', error);
  }
};

Troubleshooting

Common Issues

Android Build Issues

• Ensure your android/gradle.properties has the correct B24PaymentSdk version
• Check that your minSdkVersion is at least 24

iOS Build Issues

• Make sure your deployment target is iOS 13.0+
• Run cd ios && pod install if using bare React Native

Payment Failures

• Verify your refererKey is correct and active
• Check that you're using the correct environment (isProduction setting)
• Ensure userSyncCode or paymentMethodId are valid

Security Notes

⚠️ Important Security Considerations:

• Never hardcode production refererKey in your app
• Always validate payment results on your backend
• Use environment variables for sensitive configuration
• Implement proper error handling for failed payments
