Tajo-Brevo Integration Guide

This comprehensive guide walks you through integrating your Tajo loyalty platform with Brevo to create powerful, automated customer engagement campaigns.

Overview

The Tajo-Brevo integration enables you to:

Sync customer data in real-time between platforms
Automate loyalty campaigns based on customer behavior
Track engagement across email, SMS, and WhatsApp
Segment customers by loyalty tier and purchase behavior
Trigger personalized messages for key loyalty events

Prerequisites

Before starting the integration, ensure you have:

Tajo account with loyalty program configured
Brevo account with API access
Valid API keys for both platforms
Webhook endpoints set up for real-time sync
SSL certificate for secure data transmission

Step 1: Authentication Setup

Generate Brevo API Key

Log into your Brevo account
Go to Account & Plan > API Keys
Click Generate a new API key
Name it “Tajo Integration”
Copy and securely store the key

# Store in environment variables
export BREVO_API_KEY="xkeysib-your-api-key-here"
export TAJO_WEBHOOK_SECRET="your-webhook-secret"

Configure Tajo Integration

In your Tajo dashboard:

Go to Settings > Integrations
Select Brevo from the list
Enter your Brevo API key
Configure sync settings

{
  "brevo_api_key": "xkeysib-your-api-key-here",
  "sync_frequency": "real-time",
  "sync_contacts": true,
  "sync_orders": true,
  "sync_events": true,
  "loyalty_attributes": [
    "LOYALTY_POINTS",
    "LOYALTY_TIER",
    "TOTAL_SPENT",
    "LAST_PURCHASE"
  ]
}

Step 2: Customer Data Synchronization

Contact Sync Configuration

Set up automatic contact synchronization to keep customer data current:

// Sync customer on registration
async function syncCustomerToBrevo(customer) {
  const brevoData = {
    email: customer.email,
    attributes: {
      FIRSTNAME: customer.firstName,
      LASTNAME: customer.lastName,
      PHONE: customer.phone,
      LOYALTY_ID: customer.loyaltyId,
      LOYALTY_POINTS: customer.points,
      LOYALTY_TIER: customer.tier,
      SIGNUP_DATE: customer.createdAt,
      TOTAL_SPENT: customer.totalSpent,
      PREFERRED_CATEGORIES: customer.categories,
      BIRTHDAY: customer.birthday
    },
    listIds: [getListForTier(customer.tier)]
  };

  const response = await fetch('https://api.brevo.com/v3/contacts', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'api-key': process.env.BREVO_API_KEY
    },
    body: JSON.stringify(brevoData)
  });

  return response.json();
}

Purchase Event Sync

Automatically sync purchases to trigger loyalty campaigns:

// Sync order completion
async function syncOrderToBrevo(order, customer) {
  // Create order in Brevo
  const orderData = {
    id: order.id,
    email: customer.email,
    products: order.items.map(item => ({
      id: item.productId,
      name: item.name,
      quantity: item.quantity,
      price: item.price,
      category: item.category
    })),
    revenue: order.total,
    date: order.createdAt
  };

  await fetch('https://api.brevo.com/v3/ecommerce/orders', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'api-key': process.env.BREVO_API_KEY
    },
    body: JSON.stringify(orderData)
  });

  // Create loyalty event
  const eventData = {
    email: customer.email,
    event: 'Purchase Completed',
    properties: {
      order_id: order.id,
      amount: order.total,
      points_earned: order.pointsEarned,
      loyalty_tier: customer.tier,
      tier_upgraded: order.tierUpgraded,
      products: order.items.map(i => i.name).join(', ')
    }
  };

  await fetch('https://api.brevo.com/v3/events', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'api-key': process.env.BREVO_API_KEY
    },
    body: JSON.stringify(eventData)
  });
}

Step 3: Automated Campaign Setup

Welcome Campaign for New Customers

Create an automated welcome series for new loyalty members:

{
  "campaign_name": "Tajo Loyalty Welcome Series",
  "trigger": {
    "event": "Contact Created",
    "conditions": {
      "LOYALTY_ID": "exists",
      "SIGNUP_DATE": "today"
    }
  },
  "emails": [
    {
      "delay": "immediate",
      "template_id": 101,
      "subject": "Welcome to Tajo Loyalty! Here's your {{params.welcome_bonus}} points bonus",
      "params": {
        "welcome_bonus": "500",
        "loyalty_tier": "Bronze",
        "next_tier_points": "1000"
      }
    },
    {
      "delay": "3 days",
      "template_id": 102,
      "subject": "Don't forget to use your {{params.welcome_bonus}} bonus points!"
    },
    {
      "delay": "1 week",
      "template_id": 103,
      "subject": "Here's how to earn points faster with Tajo"
    }
  ]
}

Tier Upgrade Campaign

Automatically celebrate tier upgrades:

// Webhook handler for tier upgrades
app.post('/webhook/tier-upgrade', (req, res) => {
  const { customer, previousTier, newTier } = req.body;

  const campaignData = {
    email: customer.email,
    template_id: getTierUpgradeTemplate(newTier),
    params: {
      customer_name: customer.firstName,
      new_tier: newTier,
      previous_tier: previousTier,
      new_benefits: getTierBenefits(newTier),
      points_balance: customer.points
    }
  };

  // Send congratulations email
  sendBrevoEmail(campaignData);

  // Add to tier-specific list
  addToBrevoList(customer.email, getTierListId(newTier));

  res.status(200).json({ success: true });
});

Step 4: Loyalty Event Tracking

Key Events to Track

Set up tracking for these essential loyalty events:

const loyaltyEvents = {
  // Account Events
  'Account Created': {
    properties: ['signup_source', 'referral_code', 'welcome_bonus']
  },
  'Profile Updated': {
    properties: ['updated_fields', 'marketing_consent']
  },

  // Purchase Events
  'Purchase Completed': {
    properties: ['order_total', 'points_earned', 'loyalty_tier', 'products']
  },
  'Product Returned': {
    properties: ['return_reason', 'points_deducted', 'refund_amount']
  },

  // Loyalty Events
  'Points Earned': {
    properties: ['points_amount', 'earning_reason', 'total_balance']
  },
  'Points Redeemed': {
    properties: ['points_used', 'reward_type', 'remaining_balance']
  },
  'Tier Upgraded': {
    properties: ['previous_tier', 'new_tier', 'upgrade_benefits']
  },

  // Engagement Events
  'Email Opened': {
    properties: ['campaign_type', 'subject_line', 'device']
  },
  'Reward Browsed': {
    properties: ['reward_category', 'reward_name', 'points_required']
  },
  'Referral Made': {
    properties: ['referral_method', 'referee_email', 'referral_bonus']
  }
};

Event Tracking Implementation

class TajoBrevoEventTracker {
  constructor(apiKey) {
    this.apiKey = apiKey;
    this.baseUrl = 'https://api.brevo.com/v3';
  }

  async trackEvent(customerEmail, eventName, properties = {}) {
    const eventData = {
      email: customerEmail,
      event: eventName,
      properties: {
        timestamp: new Date().toISOString(),
        source: 'tajo_platform',
        ...properties
      }
    };

    try {
      const response = await fetch(`${this.baseUrl}/events`, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'api-key': this.apiKey
        },
        body: JSON.stringify(eventData)
      });

      if (!response.ok) {
        throw new Error(`Event tracking failed: ${response.statusText}`);
      }

      return await response.json();
    } catch (error) {
      console.error('Brevo event tracking error:', error);
      throw error;
    }
  }

  // Convenience methods for common events
  async trackPurchase(customer, order) {
    return this.trackEvent(customer.email, 'Purchase Completed', {
      order_id: order.id,
      order_total: order.total,
      currency: order.currency,
      points_earned: order.pointsEarned,
      loyalty_tier: customer.tier,
      items_count: order.items.length,
      first_purchase: customer.orderCount === 1
    });
  }

  async trackTierUpgrade(customer, previousTier) {
    return this.trackEvent(customer.email, 'Tier Upgraded', {
      previous_tier: previousTier,
      new_tier: customer.tier,
      points_balance: customer.points,
      benefits_unlocked: getTierBenefits(customer.tier),
      upgrade_date: new Date().toISOString()
    });
  }
}

Step 5: Segmentation Strategy

Customer Segments

Create targeted segments in Brevo for personalized campaigns:

const loyaltySegments = [
  // Tier-based segments
  {
    name: "Bronze Members",
    conditions: { LOYALTY_TIER: "Bronze" },
    campaigns: ["tier_upgrade_promotion", "engagement_boost"]
  },
  {
    name: "Silver Members",
    conditions: { LOYALTY_TIER: "Silver" },
    campaigns: ["premium_offers", "early_access"]
  },
  {
    name: "Gold Members",
    conditions: { LOYALTY_TIER: "Gold" },
    campaigns: ["vip_treatment", "exclusive_rewards"]
  },
  {
    name: "Platinum Members",
    conditions: { LOYALTY_TIER: "Platinum" },
    campaigns: ["luxury_experiences", "personal_offers"]
  },

  // Behavior-based segments
  {
    name: "High Spenders",
    conditions: { TOTAL_SPENT: ">1000" },
    campaigns: ["luxury_catalog", "big_spender_rewards"]
  },
  {
    name: "Frequent Shoppers",
    conditions: { PURCHASE_FREQUENCY: "weekly" },
    campaigns: ["convenience_offers", "bulk_discounts"]
  },
  {
    name: "At-Risk Customers",
    conditions: { LAST_PURCHASE: ">90 days" },
    campaigns: ["win_back", "special_incentives"]
  },
  {
    name: "Birthday Month",
    conditions: { BIRTHDAY: "this_month" },
    campaigns: ["birthday_specials", "bonus_points"]
  }
];

Step 6: Testing and Monitoring

Integration Testing Checklist

Contact Sync: New customers appear in Brevo
Order Sync: Purchases trigger events correctly
Event Tracking: All loyalty events are recorded
Campaign Triggers: Automated emails send properly
Segmentation: Customers move between lists correctly
Webhook Delivery: Real-time sync works reliably

Monitoring Setup

// Health check endpoint
app.get('/integration/health', async (req, res) => {
  const checks = {
    brevo_api: await checkBrevoConnection(),
    webhook_delivery: await checkWebhookDelivery(),
    event_tracking: await checkEventTracking(),
    campaign_triggers: await checkCampaignTriggers()
  };

  const allHealthy = Object.values(checks).every(check => check.status === 'ok');

  res.status(allHealthy ? 200 : 503).json({
    status: allHealthy ? 'healthy' : 'degraded',
    checks,
    timestamp: new Date().toISOString()
  });
});

Troubleshooting Common Issues

API Rate Limits

Brevo has rate limits - implement retry logic:

async function makeBrevoRequest(url, options, retries = 3) {
  try {
    const response = await fetch(url, options);

    if (response.status === 429) {
      const retryAfter = response.headers.get('Retry-After') || 60;
      await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
      return makeBrevoRequest(url, options, retries - 1);
    }

    return response;
  } catch (error) {
    if (retries > 0) {
      await new Promise(resolve => setTimeout(resolve, 5000));
      return makeBrevoRequest(url, options, retries - 1);
    }
    throw error;
  }
}

Data Sync Issues

Monitor and resolve sync conflicts:

// Sync conflict resolution
async function resolveSyncConflict(tajoData, brevoData) {
  // Use most recent timestamp as source of truth
  const tajoUpdated = new Date(tajoData.updatedAt);
  const brevoUpdated = new Date(brevoData.modifiedAt);

  if (tajoUpdated > brevoUpdated) {
    // Update Brevo with Tajo data
    await updateBrevoContact(brevoData.id, tajoData);
  } else {
    // Update Tajo with Brevo data
    await updateTajoCustomer(tajoData.id, brevoData);
  }
}
