Overview

The QuickPhonePe library provides an easy interface to integrate with the PhonePe payment gateway. It allows you to create and verify transactions using the PhonePe API.

Installation

To install the QuickPhonePe library, use npm:

npm install quick-phonepe

Usage

Here's a step-by-step guide on how to use the QuickPhonePe library in your Node.js project.

Import the QuickPhonePe Class

First, import the QuickPhonePe class in your project:

const QuickPhonePe = require('quick-phonepe');

Initialize the QuickPhonePe Instance

Create an instance of the QuickPhonePe class with your configuration details:

const phonePe = new QuickPhonePe({
    merchantId: 'YOUR_MERCHANT_ID',
    saltKey: 'YOUR_SALT_KEY',
    keyIndex: 1, // default is 1
    mode: 'DEV' // or 'PROD' for production
});

Create a Transaction

To create a transaction, you need to provide the transaction data. The createTransaction method returns a promise with the response from the PhonePe API.

const transactionData = {
    merchantTransactionId: 'txn_001',
    merchantUserId: 'user_001',
    name: 'John Doe',
    amount: 10000, // amount in paisa (1 INR = 100 paisa)
    redirectUrl: 'https://yourwebsite.com/callback',
    redirectMode: 'REDIRECT',
    mobileNumber: '1234567890',
    paymentInstrument: {
        type: 'PAY_PAGE'
    }
};

const response = await phonePe.createTransaction(transactionData);
console.log(response);

Verify a Transaction

To verify the status of a transaction, use the verifyTransaction method with the merchant transaction ID.

const merchantTransactionId = 'txn_001';

const response = await phonePe.verifyTransaction(merchantTransactionId);
console.log(response);
