Then run pod install

In XCode, in the project navigator:

Note for Expo Applications:

After adding the react-native-razorpay package,the option to prebuild the app must be used(this generates the android/ios platform folders in the project to use native-modules). Command for which,

npx expo prebuild

After which the application will be installed on the device/emulator.

npx expo run:[ios|android] --device

Usage

Sample code to integrate with Razorpay can be found in index.js in the included example directory.

To run the example, simply do the following in example directory and then link iOS SDK as explained in the previous section:

$ npm i

Steps

Import Razorpay module to your component:

import Razorpay from 'react-native-customui';

Call Razorpay.open method with the payment options. The method returns a JS Promise where then part corresponds to a successful payment and the catch part corresponds to payment failure.

```js
<TouchableHighlight onPress={() => {
  var options = {
    description: 'Credits towards consultation',
    currency: 'INR',
    key_id: 'rzp_test_1DP5mmOlF5G5ag',
    amount: '5000', // amount in currency subunits. Defaults to INR. 100 = 100 paise = INR 1.
    email: 'void@razorpay.com',
    contact: '9999999123',
    method: 'netbanking',
    bank: 'HDFC'
    
  }
  Razorpay.open(options).then((data) => {
    // handle success
    alert(`Success: ${data.razorpay_payment_id}`);
  }).catch((error) => {
    // handle failure
    alert(`Error: ${error.code} | ${error.description}`);
  });
}}>
```

UPI Intent flow

For using UPI Intent flow in Razorpay's React Native Custom UI plugin, you have to follow below steps.

Steps

Call getAppsWhichSupportUPI function for getting all the available apps in users phone.

Razorpay.getAppsWhichSupportUPI((data) => {
    console.log("Supported Apps",data);
});

Ensure that the upi_app_package_name is passed from the getSupportedUPIApps() method value. Otherwise, it will not pass the validation.

var options = {
  description: 'Credits towards consultation',
  currency: 'INR',
  key_id: 'rzp_test_1DP5mmOlF5G5ag',
  amount: '5000', // amount in currency subunits. Defaults to INR. 100 = 100 paise = INR 1.
  email: 'void@razorpay.com',
  contact: '9999999123',
  method: 'upi',
  upi_app_package_name : "google_pay",
  '_[flow]' : "intent"
  }

Your iOS app must seek permission from the device to open the UPI PSP app that the customer selects on the Checkout. For this, you must make the following changes in your iOS app's info.plist file.
```
<key>LSApplicationQueriesSchemes</key>
    <array>
    <string>tez</string>
    <string>phonepe</string>
    <string>paytmmp</string>
    </array>
```

A descriptive list of valid options for customui options is available here.
