Integration Guide

Step-by-step guide to integrating AuxVault into your application.

🎯 Overview

This guide walks through a complete integration from setup to going live.

Timeline: 1-2 weeks
Difficulty: Intermediate

Phase 1: Setup (Day 1)

1. Get Credentials

Contact your account manager to receive:

2. Install SDK

# Node.js
npm install @auxvault/node

# PHP
composer require auxvault/php-sdk

# Python
pip install auxvault

3. Configure Environment

# .env.development
LUQRA_API_KEY=test_abc123...
LUQRA_TENANT_ID=tenant_test_456
LUQRA_ENVIRONMENT=sandbox

# .env.production
LUQRA_API_KEY=live_xyz789...
LUQRA_TENANT_ID=tenant_live_789
LUQRA_ENVIRONMENT=production

Phase 2: Basic Integration (Days 2-3)

1. Initialize Client

const AuxVault = require('@auxvault/node');

const client = new AuxVault({
  apiKey: process.env.LUQRA_API_KEY,
  tenantId: process.env.LUQRA_TENANT_ID,
  environment: process.env.LUQRA_ENVIRONMENT
});

2. Process First Transaction

async function processPayment(paymentData) {
  try {
    const transaction = await client.transactions.create({
      type: 'sale',
      amount: paymentData.amount,
      currency: 'USD',
      card: paymentData.card,
      billing: paymentData.billing,
      customer: paymentData.customer
    });
    
    return { success: true, transaction };
  } catch (error) {
    return { success: false, error };
  }
}

3. Handle Response

const result = await processPayment(paymentData);

if (result.success) {
  // Payment approved
  console.log('Transaction ID:', result.transaction.id);
  // Send receipt, update order status, etc.
} else {
  // Payment failed
  console.error('Error:', result.error.message);
  // Show error to customer
}

Phase 3: Error Handling (Day 4)

Implement Comprehensive Error Handling

function handlePaymentError(error) {
  switch (error.code) {
    case 'TRANSACTION_DECLINED':
      return 'Payment declined. Please try a different card.';
    
    case 'INSUFFICIENT_FUNDS':
      return 'Insufficient funds. Please try a different card.';
    
    case 'INVALID_CARD':
      return 'Invalid card details. Please check and try again.';
    
    case 'VALIDATION_ERROR':
      return `Invalid ${error.field}: ${error.message}`;
    
    default:
      return 'Payment processing error. Please try again.';
  }
}

Phase 4: Webhooks (Day 5)

1. Create Webhook Endpoint

app.post('/webhooks/auxvault', async (req, res) => {
  const signature = req.headers['x-luqra-signature'];
  const isValid = client.webhooks.verify(req.body, signature);
  
  if (!isValid) {
    return res.status(401).send('Invalid signature');
  }
  
  const event = req.body;
  
  switch (event.type) {
    case 'transaction.approved':
      await handleTransactionApproved(event.data);
      break;
    
    case 'transaction.declined':
      await handleTransactionDeclined(event.data);
      break;
    
    case 'refund.approved':
      await handleRefundApproved(event.data);
      break;
  }
  
  res.sendStatus(200);
});

2. Register Webhook

curl -X POST https://dev.auxcore.net/api/v1/webhooks \
  -d '{
    "url": "https://your-app.com/webhooks/auxvault",
    "events": ["transaction.approved", "transaction.declined", "refund.approved"]
  }'

Phase 5: Refunds (Day 6)

async function processRefund(transactionId, amount, reason) {
  try {
    const refund = await client.transactions.refund(transactionId, {
      amount,
      reason
    });
    
    return { success: true, refund };
  } catch (error) {
    return { success: false, error };
  }
}

Phase 6: Testing (Days 7-10)

Test Scenarios

  1. Successful payment
  2. Declined payment
  3. Partial refund
  4. Full refund
  5. AVS mismatch
  6. CVV mismatch
  7. Webhook delivery
  8. Error handling

Phase 7: Production Setup (Days 11-12)

1. Update Configuration

// Update to production credentials
const config = {
  apiKey: process.env.LUQRA_API_KEY_PROD,
  tenantId: process.env.LUQRA_TENANT_ID_PROD,
  environment: 'production'
};

2. Test in Production

Process small test transaction to verify.

3. Enable Monitoring

// Add error tracking
const Sentry = require('@sentry/node');
Sentry.init({ dsn: 'YOUR_DSN' });

// Log all transactions
client.on('transaction', (txn) => {
  logger.info('Transaction:', txn.id);
});

Phase 8: Go Live (Days 13-14)

  1. Enable production mode
  2. Monitor closely
  3. Have rollback plan ready
  4. Provide customer support
