React Native SDK

Integrating PayHere with your React Native Mobile App is super easy with our PayHere React Native SDK. You just have to include the package in your project dependencies, call its methods to initiate a payment and fetch the payment status just after the payment. The beauty is, this SDK allows you to accept a payment within your app, without redirecting your app user to the web browser.

Please refer the below steps to integrate PayHere React Native SDK to your Mobile App.

1. Include PayHere Mobile SDK in your App

Open your React Native project's package.json file and add the PayHere React Native SDK dependency.

{
  "dependencies": {
    "@payhere/payhere-mobilesdk-reactnative": "1.0.5"
  }
}

Then run the following commands in your React Native project directory.

npm install
react-native link @payhere/payhere-mobilesdk-reactnative


2. Set Android Pre-requisites

a. Add the PayHere Android SDK's Maven repository

Open up the (outermost) build.gradle file in your Android project and add the repository.

allprojects {
    repositories {
        mavenLocal()
        maven {
            url  "https://dl.bintray.com/payhere/payhere-android-payment"
        }
    }
}

b. Allow Manifest attribute merge

Open up the AndroidManifest.xml file in your Anrdoid project and make the following changes.

i. Declare the Android tools namespace in the element.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.domain.name"
    xmlns:tools="http://schemas.android.com/tools">

ii. Add the replace merge rule for the android:allowBackup attribute in the element.

<application tools:replace="android:allowBackup">


3. Set iOS Pre-requisites

Open up the Podfile file in your iOS project and make the following changes.

a. Increase the platform version to iOS 11.

platform :ios, '11.0'

b. Add this line just below 'use_react_native!'

pod 'payhere-mobilesdk-reactnative', :path => '../node_modules/@payhere/payhere-mobilesdk-reactnative'


4. Whitelist Mobile App Package Name

a. Login to your PayHere Merchant Account and navigate to Settings > Domains & Credentials.

b. Click the 'Add Domain/App' button.

c. Select 'App' from the first dropdown.

d. Add your React Native App package name (e.g. lk.bhasha.helakuru).

e. Take note of the hash value in the last field. This is your Merchant Secret for this specific mobile App. You will need this in Step 5.

f. Click 'Request to Approve'.

(If you are using a PayHere Live Merchant Account, your App Package Name must be manually reviewed & approved. Please allow upto one business day for this review process to complete.)


5. Initiate a Payment Request to PayHere Payment Gateway

a. One-time Payment Request

Creates a one-time payment request charged only once. To capture the payment details from your server, read our docs.

import { Alert } from 'react-native';
import PayHere from '@payhere/payhere-mobilesdk-reactnative';

const paymentObject = {
    "sandbox": true,                 // true if using Sandbox Merchant ID
    "merchant_id": "1211149",        // Replace your Merchant ID
    "merchant_secret": "xyz",        // See step 4e
    "notify_url": "http://sample.com/notify",
    "order_id": "ItemNo12345",
    "items": "Hello from React Native!",
    "amount": "50.00",
    "currency": "LKR",
    "first_name": "Saman",
    "last_name": "Perera",
    "email": "samanp@gmail.com",
    "phone": "0771234567",
    "address": "No.1, Galle Road",
    "city": "Colombo",
    "country": "Sri Lanka",
    "delivery_address": "No. 46, Galle road, Kalutara South",
    "delivery_city": "Kalutara",
    "delivery_country": "Sri Lanka",
    "custom_1": "",
    "custom_2": ""
};

PayHere.startPayment(
    paymentObject, 
    (paymentId) => {
        console.log("Payment Completed", paymentId);
    },
    (errorData) => {
        Alert.alert("PayHere Error", errorData);
    },
    () => {
        console.log("Payment Dismissed");
    }
);


b. Recurring Payment Request

Creates a subscription payment that is charged at a fixed frequency. To capture the payment details from your server, read our docs. You can learn more about PayHere Recurring Payments in our docs.

import { Alert } from 'react-native';
import PayHere from '@payhere/payhere-mobilesdk-reactnative';

const paymentObject = {
    "sandbox": true,                 // true if using Sandbox Merchant ID
    "merchant_id": "1211149",        // Replace your Merchant ID
    "merchant_secret": "xyz",        // See step 4e
    "notify_url": "http://sample.com/notify",
    "order_id": "ItemNo12345",
    "items": "Hello from React Native!",
    "amount": "50.00",               // Recurring amount
    "recurrence": "1 Month",         // Recurring payment frequency
    "duration": "1 Year",            // Recurring payment duration
    "startup_fee": "10.00",          // Extra amount for first payment
    "currency": "LKR",
    "first_name": "Saman",
    "last_name": "Perera",
    "email": "samanp@gmail.com",
    "phone": "0771234567",
    "address": "No.1, Galle Road",
    "city": "Colombo",
    "country": "Sri Lanka",
    "delivery_address": "No. 46, Galle road, Kalutara South",
    "delivery_city": "Kalutara",
    "delivery_country": "Sri Lanka",
    "custom_1": "",
    "custom_2": ""
};

PayHere.startPayment(
    paymentObject, 
    (paymentId) => {
        console.log("Payment Completed", paymentId);
    },
    (errorData) => {
        Alert.alert("PayHere Error", errorData);
    },
    () => {
        console.log("Payment Dismissed");
    }
);


c. Preapproval Request

Tokenize customer card details for later usage with the PayHere Charging API. To capture the payment details from your server, read our docs. You can learn more about PayHere Automated Charging in our docs.

import { Alert } from 'react-native';
import PayHere from '@payhere/payhere-mobilesdk-reactnative';

const paymentObject = {
    "sandbox": true,                 // true if using Sandbox Merchant ID
    "preapprove": true,              // Required
    "merchant_id": "1211149",        // Replace your Merchant ID
    "merchant_secret": "xyz",        // See step 4e
    "notify_url": "http://sample.com/notify",
    "order_id": "ItemNo12345",
