Integrate with React Native SDK

You can use PortOne SDK to integrate the PortOne Payment Gateway with your React native Application.

Video Tutorial

Sample App

Check the sample app to integrate on GitHub

Prerequisites

• Create an account on PortOne
• Enable Payment Channels and Methods which you want to use
• Login to the portone portal where you can access the API Keys (client key and secret key) for integrations under Settings -> API tab.

Integration

Steps to integrate your React native application with PortOne React native SDK.

1. Enable deep link in iOS

1. To open your application, add the url schemes to the app, Go to ProjectSettings -> info

2. Add url schemes and identifier inside the URL types.
   You can see the scheme and identifier details in info.plist as below:

   ```json
   <key>CFBundleURLTypes</key>
   <array>
   		<dict>
   			<key>CFBundleTypeRole</key>
   			<string>Editor</string>
   			<key>CFBundleURLName</key>
   			<string>checkout</string>
   			<key>CFBundleURLSchemes</key>
   			<array>
   				<string>portone</string>
   			</array>
   		</dict>
   	</array>
   ```
   

3. To open the other applications, should include the url schemes in info.plist

   JSON

   <key>LSApplicationQueriesSchemes</key>
   	<array>
   		<string>itms-appss</string>
   		<string>zalopay</string>
   		<string>line</string>
   		<string>ascendmoney</string>
   	</array>
   

   LSApplicationQueriesSchemes - Specifies the URL schemes you want the app to be able to use with the canOpenURL: method of the UIApplication class.

4. To support HTTP connections, add this source code in app info.plist

   JSON

   <key>NSAppTransportSecurity</key>
   	<dict>
   		<key>NSAllowsArbitraryLoads</key>
   		<true/>
   		<key>NSAllowsLocalNetworking</key>
   		<true/>
   		<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
   		<true/>
   	</dict>
   

2. Enable deep link in ANDROID

1. To create a link to your app content, add an intent filter that contains these elements and attribute values in your AndroidManifest.xml:

2. Include the BROWSABLE category. It is required in order for the intent filter to be accessible from a web browser. Without it, clicking a link in a browser cannot resolve to your app.

   Also include the DEFAULT category. This allows your app to respond to implicit intents. Without this, the activity can be started only if the intent specifies your app component name.

   JSON

   ```java
   <category android:name="android.intent.category.DEFAULT" />
   <category android:name="android.intent.category.BROWSABLE" />
   

To accept the URIs that begin with portone://checkout“

if redirectionUrl= "**portone://checkout"**
then host = "**checkout"**

     `scheme = "**portone"**`

<intent-filter>
       <action android:name="android.intent.action.VIEW" />
       <category android:name="android.intent.category.DEFAULT" />
       <category android:name="android.intent.category.BROWSABLE" />

                <data
                    android:host="checkout"
                    android:scheme="portone" />
</intent-filter>

3. Add following steps to use the librbary

1. Add .npmrc file to the project directory

2. In that file, add the following code and save it

   JSX

   @iamport-intl:registry=https://npm.pkg.github.com/
   //npm.pkg.github.com/:_authToken=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
   

3. Go to project terminal, run the following code

   JSX

   npm install @iamport-intl/portone-sdk@latest
   

   After successful installation, it will be shown in package.json under dependencies

4. Add peer dependencies

   JSX

   npm install @react-native-async-storage/async-storage
   npm install react-native-localization
   npm install react-native-webview
   npm install react-native-linear-gradient
   npm install react-native-rsa-native
   

4. Have a setup to get JWT token from the server

On the server side, a JWT token must be constructed that accepts portoneKey as input. Further information on JWT token generation is described in the link below.

Authentication | PortOne

5. Generate Signture Hash

Generate a Signature Hash using HmacSHA256 which needs to be included in the payload.

createHash = (
    key,
    amount,
    currency,
    failureUrl,
    merchantOrderId,
    successUrl,
    secretKey,
  ) => {
    let mainParams =
      'amount=' +
      encodeURIComponent(amount) +
      '&client_key=' +
      encodeURIComponent(key) +
      '&currency=' +
      encodeURIComponent(currency) +
      '&failure_url=' +
      encodeURIComponent(failureUrl) +
      '&merchant_order_id=' +
      encodeURIComponent(merchantOrderId) +
      '&success_url=' +
      encodeURIComponent(successUrl);
    console.log('currency', currency);
    let hash = HmacSHA256(mainParams, secretKey);
    let signatureHash = Base64.stringify(hash);
    return signatureHash;
  };

6. Initialise PortOne RN SDK and authorise it.

1. Import library of portone SDK

import {Checkout} from '@iamport-intl/chaiport-sdk';

1. Initialize the checkout instance as below:

<Checkout
          callbackFunction={this.afterCheckout}
          redirectUrl={"chaiport://"}
          environment={"sanbox"} //Optional
/>

Checkout using web

1. To get the payment link to use the SDK checkout UI, call the openCheckoutUI method from SDK as below:

   JSX

   let response = await helpers.getOTP(mobileNumber);
   

2. Web view response will be given back to the callbackFunction

   Swift

   afterCheckout = transactionDetails => {
       console.log('Response from webview', transactionDetails);
       // Do the needful
     };
   

Sample JWT Token

let jwtToken = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJDSEFJUEFZIiwic3ViIjoibHpyWUZQZnlNTFJPYWxsWiIsImlhdCI6MTYzMjM5MDkyMCwiZXhwIjoyNzMyMzkwOTIwfQ.IRgiM-zjAdJEVDuPSNfxmDszZQi_csE1q7xjVRvPvoc';

Sample Response

let response = await helpers.fetchSavedCards(
    mobileNumber,
    OTP
);

Sample response :

• Success Case

{
"is_success": "true",
"status_code": "2000",
"status_reason": "SUCCESS",
"merchant_order_ref": "MERCHANT1234567890",
"channel_order_ref": "PAY-FylBOXjbTMmH52CCNI4OFw"
}

• Failure case

{
"is_success": "false",
"message": "Received error from Baokim Server: customer_phone=>The customer phone format is invalid., ",
"status_code": "5000",
"status_reason": "PAYMENT_SYSTEM_ERROR"
}

Payload

All of the web checkout request's parameters are listed here, along with the appropriate data type.

**MerchantDetails**

**BillingDetails**

**ShippingDetails**

Probable Errors:

INVALID_UNAUTHORIZED_JWT_TOKEN_ERROR

1. Check whether PortOne Key and the Secret Key are of the same account
2. Check whether the Secret Key is not modified
3. Check whether Bearer keyword is added before the generated token with a white space. Bearer $jwtToken
4. Verify if the expiration time should be greater than the current time

INVALID_UNAUTHORISED_TRANSACTION_SIGNATURE_ERROR

1. Check whether all params match with the payload/request
2. Check whether the portone key match with the payload and the account

INVALID_UNAUTHORISED_TRANSACTION_IAMPORTKEY_ERROR

1. Check whether the portone key match with the payload and the account

INVALID_PAYMENT_CHANNEL

1. Make sure the payment channels and payment methods which are added in the payload are enable from the portone portal

INVALID_ENVIRONMENT

1. Make sure you have added environment either sandbox or live

Summation of order value, tax, duties, shipping and discount is equal to amount

1. If items are provided then please verify the values provided should match the total amount: sum(items price * items quantity) + shipping charge - discount = amount
2. Mandatory params in payload:

price
promo_discount       (0 is also acceptable)
shipping_charges     (0 is also acceptable)
