Introduction

The FawryPay React Native SDK provides seamless integration for processing payments and managing cards within your React Native application. This guide will walk you through the steps needed to integrate the SDK into your project.

Note: Currently, the FawryPay React Native SDK does not support EXPO projects. Please use Vanilla React Native for integration.

How it works

Installation

To get started with the FawryPay SDK, follow these installation steps:

Step 1: Install the FawryPay SDK

To install the FawryPay SDK, use npm:

npm install @fawry_pay/rn-fawry-pay-sdk --save

For React Native versions prior to 0.60, link the package using react-native link:

react-native link @fawry_pay/rn-fawry-pay-sdk

For React Native versions 0.60 and above, autolinking will handle linking.

Getting Started

Step 1: Create a FawryPay Account

Before utilizing the FawryPay SDK, you must have a FawryPay account. Visit the FawryPay website to create an account if you don't already have one.

Step 2: Initialize the SDK

In your React Native project, import the necessary components and configure the FawryPay SDK with your items, merchant and customer information:

import React, { useEffect } from 'react';
import { TouchableOpacity, Text, StyleSheet, View, Platform } from 'react-native';
import * as Fawry from '@fawry_pay/rn-fawry-pay-sdk';
import uuid from 'react-native-uuid';

const cartItems : Fawry.BillItems[] = [
  { itemId: 'item1', description: 'Item 1 Description', quantity: '10', price: '30' },
  { itemId: 'item2', description: 'Item 2 Description', quantity: '5', price: '20' },
  { itemId: 'item3', description: 'Item 3 Description', quantity: '1', price: '10' },
];

const merchant : Fawry.MerchantInfo = {
  merchantCode: 'YOUR MERCHANT CODE',
  merchantSecretCode: 'YOUR SECRET CODE',
  merchantRefNum: uuid.v4().toString(),
};

const customer : Fawry.CustomerInfo = {
  customerName: 'Ahmed Kamal',
  customerMobile: '+1234567890',
  customerEmail: '[email protected]',
  customerProfileId: '12345',
};

const fawryConfig : Fawry.FawryLaunchModel = {
  baseUrl: 'https://atfawry.fawrystaging.com/',
  lang: Fawry.FawryLanguages.ENGLISH,
  signature: '',
  allow3DPayment: false,
  skipReceipt: false,
  skipLogin: true,
  payWithCardToken: true,
  authCaptureMode: false,
  allowVoucher: true,
  items: cartItems,
  merchantInfo: merchant,
  customerInfo: customer,
};
// Continue with the code...

Step 3: Present Payment Options

To initiate the payment process, use the startPayment function to open the payment flow.

// Launch the payment flow
Fawry.startPayment(fawryConfig);

Step 4: Present Card Manager (Optional)

If you want to allow your users to manage their saved cards, you can use the openCardsManager function:

// Open the card manager flow
Fawry.openCardsManager(
  fawryConfig.baseUrl,
  fawryConfig.language,
  fawryConfig.merchantInfo,
  fawryConfig.customerInfo
);

Step 5: Callbacks (Optional)

The FawryPay SDK provides event listeners that you can use to receive payment and card manager status. Here's how to set up event listeners:

// Define event listeners for payment and card manager events
const eventListeners = [
  { eventName: Fawry.FawryCallbacks.FAWRY_EVENT_PAYMENT_COMPLETED, listener: (data: any) => console.log(Fawry.FawryCallbacks.FAWRY_EVENT_PAYMENT_COMPLETED, data) },
  { eventName: Fawry.FawryCallbacks.FAWRY_EVENT_ON_SUCCESS, listener: (data: any) => console.log(Fawry.FawryCallbacks.FAWRY_EVENT_ON_SUCCESS, data) },
  { eventName: Fawry.FawryCallbacks.FAWRY_EVENT_ON_FAIL, listener: (error: any) => console.log(Fawry.FawryCallbacks.FAWRY_EVENT_ON_FAIL, error) },
  { eventName: Fawry.FawryCallbacks.FAWRY_EVENT_CardManager_FAIL, listener: (error: any) => console.log(Fawry.FawryCallbacks.FAWRY_EVENT_CardManager_FAIL, error) },
];

// Attach event listeners
const attachEventListeners = () => eventListeners.forEach(({ eventName, listener }) => Fawry.FawryCallbacks.FawryEmitter.addListener(eventName, listener));


// Detach event listeners when the component unmounts
const detachEventListeners = () => eventListeners.forEach(({ eventName }) => Fawry.FawryCallbacks.FawryEmitter.removeAllListeners(eventName));


useEffect(() => {
  attachEventListeners();

  // Clean up event listeners when the component unmounts
  return detachEventListeners;
}, []);

Platform-specific Notes

Android

For Android integration, follow these additional steps:

1. Open the build.gradle file located in the root of your Android project (named android/build.gradle).

2. Find the buildscript block and add the following code in it:

   allprojects {
       repositories {
         google()
         mavenCentral()
         maven { url "https://nexus.mobile.fawry.io/repository/maven-releases/" }
         maven { url "https://maven.google.com" }
         jcenter()
       }
     }

These changes enable your Android project to resolve dependencies from the specified repositories, facilitating the installation and usage of the @fawry_pay/rn-fawry-pay-sdk package in your React Native application.

iOS

For iOS integration, ensure that you follow these steps:

1. Open the Podfile file located in the root of your iOS project.

2. Delete the following code block:

   flipper_config = ENV['NO_FLIPPER'] == "1" ? FlipperConfiguration.disabled : FlipperConfiguration.enabled
      
   linkage = ENV['USE_FRAMEWORKS']
   if linkage != nil
     Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
     use_frameworks! :linkage => linkage.to_sym
   end

3. Replace the removed code with:

   use_frameworks!

4. Disable Hermes Engine by changing:

   :hermes_enabled => flags[:hermes_enabled],

   to:

   :hermes_enabled => false,

5. Disable Flipper by changing:

   :flipper_configuration => flipper_config,

   to:

   :flipper_configuration => FlipperConfiguration.disabled,

6. In your iOS directory , run the command pod install

Note for Xcode 15 Users:

If you are using Xcode 15, it's important to follow these additional steps for proper integration:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
    end
  end
  react_native_post_install(
    installer,
    config[:reactNativePath],
    :mac_catalyst_enabled => false
  )
  __apply_Xcode_12_5_M1_post_install_workaround(installer)
end

After adding this code snippet, remember to run pod update in your iOS directory to ensure that the changes are properly applied.

These changes enable your iOS project to integrate the latest podfile without issues, facilitating the installation and usage of the @fawry_pay/rn-fawry-pay-sdk package in your React Native application.

Important Reminder: If you're conducting tests on an Apple Silicon Mac, make sure that you're using the iPhone simulator with Rosetta. To do this, follow these steps: Open Xcode, go to Product > Destination > Destination Architectures > Show Rosetta Destination, and then select a Rosetta iPhone Simulator for running the application.

Customizing UI Colors

Android

To customize UI colors for Android:

1. Navigate to android > app > src > main > res > values.

2. Create a new file named colors.xml.

3. Add color values to colors.xml:

   <?xml version="1.0" encoding="utf-8"?>
   <resources>
       <color name="fawry_blue">#6F61C0</color>
       <color name="fawry_yellow">#A084E8</color>
   </resources>

iOS

For iOS UI color customization:

1. In your project, navigate to ios > YourAppNampe.

2. Create a new file named Style.plist.

3. Add color values to Style.plist:

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
    <key>primaryColorHex</key>
    <string>#6F61C0</string> <!-- Set your primary color hex code -->
    <key>secondaryColorHex</key>
    <string>#A084E8</string> <!-- Set your secondary color hex code -->
    <key>tertiaryColorHex</key>
    <string>#8BE8E5</string> <!-- Set your tertiary color hex code -->
    <key>headerColorHex</key>
    <string>#6F61C0</string> <!-- Set your header color hex code -->
   </dict>
   </plist>

   Then, add the Style.plist file to your Xcode project.
