Unofficial PayHero Node.js SDK

Welcome to the unofficial PayHero Node.js SDK, this SDK provides a convenient way to integrate PayHero and Pesapal payment functionality into your Node.js applications.

Installation

You can install the PayHero Node.js SDK via npm:

npm i payhero-wrapper

Usage

First, import the PayHero class:

import PayHero from 'payhero-wrapper';

Then, initialize PayHero with your API keys:

const PayHeroConfig = {
  Authorization: 'your_PayHero_authorization_token',
  pesapalConsumerKey: 'your_pesapal_consumer_key',
  pesapalConsumerSecret: 'your_pesapal_consumer_secret',
  pesapalApiUrl: 'https://payments.pesapal.com/pesapalv3/api', // Sandbox or production URL
  pesapalCallbackUrl: 'https://your-application.com/pesapal-callback',
  pesapalIpnId: 'your_pesapal_ipn_id'
};

const PayHero = new PayHero(PayHeroConfig);

Making STK Push Payments

const paymentDetails = {
    amount: 10,
    phone_number: "0740161331",
    channel_id: 333,
    provider: "m-pesa",
    external_reference: "INV-009",
    callback_url: "https://example.com/callback.php"
};

PayHero.makeStkPush(paymentDetails)
    .then(response => console.log(response))
    .catch(error => console.error(error));

Initiating Pesapal Payments

const pesapalPaymentDetails = {
    currency: 'KES',
    amount: 1000,
    description: 'Test payment',
    customerEmail: '[email protected]',
    customerFirstName: 'John',
    customerLastName: 'Doe',
    phoneNumber: '0712345678',
    countryCode: 'KE'
};

const { orderTrackingId, merchantReference, redirectUrl } = await PayHero.initiatePesapalPayment(pesapalPaymentDetails);
console.log('Pesapal payment initiated:');
console.log('Order Tracking ID:', orderTrackingId);
console.log('Merchant Reference:', merchantReference);
console.log('Redirect URL:', redirectUrl);

// Redirect the user to the Pesapal payment page
you can use the redirectUrl to open it on your app or give users to open and make the payment;

Verifying Pesapal Transactions

const paymentStatus = await PayHero.verifyPesapalTransaction('your_order_tracking_id');
console.log('Pesapal transaction status:', paymentStatus);

Retrieving Payment Channels, Banks, Wallet Balances, Transactions, and more

The SDK provides the following additional functions:

• paymentChannels()
• createPaymentChannel(channelDetails)
• getBanks()
• serviceWalletBalance()
• paymentsWalletBalance()
• topUpServiceWallet(topUpDetails)
• accountTransactions()
• transactionStatus(transactionId)
• withdraw(withdrawalDetails)

  pesapalConsumerKey: 'your_pesapal_consumer_key',
  pesapalConsumerSecret: 'your_pesapal_consumer_secret',
  pesapalApiUrl: 'https://payments.pesapal.com/pesapalv3/api', // Sandbox or production URL
