Komoju SDK for React Native

Welcome to the Komoju Payment Gateway SDK! This SDK empowers you to seamlessly integrate secure payment processing into your Android and iOS apps using React Native.

Getting Started

Get started with our Developer-oriented API documentation or example project

Installation

yarn add @komoju/komoju-react-native
or
npm install @komoju/komoju-react-native

In order to use the SDK you will have to install bellow packages as dependencies.

i18next
react-i18next

Usage example

// App.ts
import { KomojuSDK } from "@komoju/komoju-react-native";

function App() {
  return (
    <KomojuSDK.KomojuProvider publishableKey={PUBLISHABLE_KEY}>
      <PaymentScreen />
    </KomojuSDK.KomojuProvider>
  );
}

// PaymentScreen.ts
import { KomojuSDK } from "@komoju/komoju-react-native";

export default function PaymentScreen() {
  const { createPayment } = KomojuSDK.useKomoju();

  const checkout = async () => {
    createPayment({
      sessionId, // retrieve this from your server
      onComplete, // (optional) pass a callback to get the final results of response when payment is complete
    });
  };

  return (
    <View>
      <Button title="Checkout" onPress={checkout} />
    </View>
  );
}

Komoju initialization

You can visit our docs to see how a session id can be created

Setup a return URL.

Many payment method types require a return URL, so if you fail to provide it, we can’t present those payment methods to your user, even if you’ve enabled them. When a customer exits your app, for example to authenticate in Safari or their banking app, provide a way for them to automatically return to your app afterward.

1. Use return_url parameter when creating a session

2. Configure the custom URL scheme in your AndroidManifest.xml and Info.plist files

Note: If you’re using Expo, set your scheme in the app.json file.

To initialize Komoju in your React Native app, use the KomojuSDK.KomojuProvider component in the root component of your application.

KomojuProvider can accept publishableKey, paymentMethods and language as props. Only publishableKey is required.

import {
  KomojuSDK,
  PaymentTypes,
  LanguageTypes,
} from "@komoju/komoju-react-native";

function App() {
  const [publishableKey, setpublishableKey] = useState("");

  const fetchpublishableKey = async () => {
    const key = await fetchKey(); // fetch key from your server here
    setpublishableKey(key);
  };

  useEffect(() => {
    fetchpublishableKey();
  }, []);

  return (
    <KomojuSDK.KomojuProvider
      publishableKey={publishableKey}
      paymentMethods={[PaymentTypes.KONBINI]} // explicitly set the payment method(s) for purchase
      language={LanguageTypes.JAPANESE} // explicitly set the language, if not set language will be picked from your session Id
    >
      // Your app code here
    </KomojuSDK.KomojuProvider>
  );
}
