JazzCash Node.js Integration

Disclaimer: This is an unofficial JazzCash API Payment Gateway integration. This repository aims to assist developers in streamlining the integration process. For official information, please refer to the JazzCash Online Payment Gateway. This package facilitates the hosted checkout process and does not currently support subscription options.

About

JazzCash is a leading payment gateway in Pakistan, enabling businesses to securely accept online payments. It offers fast transaction processing, advanced fraud protection, and a user-friendly interface, making it ideal for small business owners, e-commerce stores, and developers integrating payment gateways into websites or mobile apps. This document provides detailed instructions for integrating JazzCash's hosted checkout feature (version 1.0.0).

Intended Audience

This guide is for merchants and developers seeking to integrate JazzCash's hosted checkout into their applications.

Integration Scope

Merchants are responsible for implementing all e-commerce functionality. JazzCash services are utilized solely for payment processing via the hosted checkout feature.

API Endpoints

This package supports only the hosted checkout process; direct checkout API endpoints are not included.

Integration Prerequisites

Prior to integration, merchants must register with JazzCash. Upon registration, the following credentials will be provided:

• Merchant_ID
• Password
• Hashkey
• Sandbox URL
• Production URL

These credentials are essential for obtaining a one-time authentication token.

Installation

Install the package via npm:

npm install @zfhassaan/jazzcash

Configuration

Create a configuration file (e.g., config.js) and set the following parameters:

module.exports = {
  paymentMode: 'sandbox', // or 'production'
  merchantId: 'YOUR_MERCHANT_ID',
  password: 'YOUR_PASSWORD',
  hashKey: 'YOUR_HASHKEY',
  mpin: 'YOUR_MPIN',
  productionUrl: 'YOUR_PRODUCTION_URL',
  sandboxUrl: 'YOUR_SANDBOX_URL',
  returnUrl: 'YOUR_RETURN_URL',
};

Usage

In your application, require the JazzCash module and use it as follows:

const JazzCash = require('jazzcash-nodejs');
const config = require('./config');

const jazzcash = new JazzCash(config);

const transactionData = {
  amount: 1000, // Amount in paisa (e.g., 1000 paisa = 10 PKR)
  billReference: 'bill-reference',
  productDescription: 'Product Description',
};

jazzcash.initiateTransaction(transactionData)
  .then(response => {
    // Handle the response, e.g., render the HTML form
  })
  .catch(error => {
    // Handle errors
  });

Steps

1. Hosted Checkout:
   • Send a POST request with the following parameters:

     {
       "amount": "1",
       "billref": "bill-reference",
       "productDescription": "Product Description"
     }

   • In your controller:

     const jazzcash = new JazzCash(config);
     jazzcash.setAmount(request.body.amount);
     jazzcash.setBillReference(request.body.billref);
     jazzcash.setProductDescription(request.body.productDescription);
     return jazzcash.sendRequest();

   • The sendRequest method sends a request to the JazzCash API to initiate the checkout process and returns the response as an HTML template, which can be rendered on web and mobile applications. Use CSS to control the visibility of fields on the frontend.

Testing

• Sandbox Mode: Set paymentMode to 'sandbox' in your configuration to test the checkout process without processing actual payments.
• Production Mode: Set paymentMode to 'production' in your configuration to process live transactions.
