Installation

npm install tranzilajs

Getting Started

Prerequisites

  • Node.js: 18.0.0 or higher
  • npm: 8.0.0 or higher
  • Tranzila Account: Merchant account with terminal credentials
  • Terminal Credentials: Terminal name, public key, and private key

Basic Setup

import { Tranzila } from 'tranzilajs';

// Initialize the client with your credentials
const tranzila = new Tranzila(
  'your-terminal-name',    // From your Tranzila dashboard
  'your-public-key',       // From your Tranzila dashboard
  'your-private-key'       // From your Tranzila dashboard
);

Quick Start Example

// Simple Bit payment initialization
const result = await tranzila.Bit.init({
  terminal_name: 'myterminal',        // Use your actual terminal name
  txn_currency_code: "ILS",
  txn_type: "debit",
  success_url: 'https://your-site.com/success',
  failure_url: 'https://your-site.com/failure',
  notify_url: 'https://your-site.com/notify',
  client: {
    name: 'John Doe',
    email: 'john.doe@example.com',
  },
  items: [{
    name: 'Product',
    type: "I",
    unit_price: 100,
    units_number: 1,
    currency_code: "ILS"
  }]
});

if (result.error_code === 0) {
  console.log('Payment URL:', result.sale_url);
  // Redirect user to result.sale_url for payment or render in an iframe
} else {
  console.error('Error:', result.message);
}

JavaScript Usage

const { Tranzila } = require('tranzilajs');

const tranzila = new Tranzila(
  'your-terminal-name',
  'your-public-key',
  'your-private-key'
);

// All methods work the same way
const result = await tranzila.Bit.init({...});

Callback Handling

When payments are completed, Tranzila sends POST requests to your configured URLs. These webhooks provide real-time updates about payment status and completion.

When Callbacks Are Sent

  • Bit Payments: After user completes payment on the Bit payment page
  • Credit Card Payments: After successful/failed credit card processing
  • Standing Orders: When recurring charges are processed

Callback Types

  • Notify Callbacks (notify_url): Real-time payment status updates sent to your server
  • Success Callbacks (success_url): User redirected after successful payment
  • Failure Callbacks (failure_url): User redirected after failed payment

Implementing Notify Callback

// Example Express.js callback handler
app.post('/notify', (req, res) => {
  const callbackData = req.body;
  
  if (callbackData.Response === '000') {
    // Payment successful
    console.log('Payment completed:', callbackData);
    // Update your database, send confirmation emails, etc.
  } else {
    // Payment failed
    console.log('Payment failed:', callbackData);
    // Handle failure (update your database, notify user, etc.)
  }
  
  res.status(200).send('OK');
});

Example Callback Data
