Server-side Integration (Recommended)

Server-side tracking is the recommended method for conversion tracking because it:

✅ Can’t be blocked by ad blockers
✅ Guarantees delivery of tracking events
✅ Confirms actions before tracking (e.g., payment verified)
✅ Works with webhooks from payment providers

How It Works

Prerequisites

Important: For conversion tracking to work, users must arrive on your website via a Taapit deeplink. This is how the tracking ID (ta_tid) is generated and passed to your site.

Before you start:

Create a Taapit deeplink pointing to your website or landing page
Enable conversion tracking on your link:
- Go to your link settings in the Taapit dashboard
- Enable Conversion Tracking
Get your Secret Key from Settings → Conversion in your Taapit dashboard

Never expose your secret key in client-side code. Use it only on your server.

Installation

Even for server-side tracking, you must install the SDK on your frontend to capture the ta_tid cookie.

NPM Package (React/Next.js)
Script Tag + REST API

Step 1: Frontend - Install the SDK

npm install taapit-sdk

Add the Analytics component to capture ta_tid:

app/layout.tsx

import { Analytics } from "taapit-sdk/react";

export default function RootLayout({ children }) {
  return (
    <html>
      <body>
        {children}
        <Analytics />
      </body>
    </html>
  );
}

Step 2: Backend - Set up your API key

.env

TAAPIT_API_KEY=taapit_sk_xxx

Never expose your secret API key in client-side code.

Step 3: Backend - Track conversions

app/api/signup/route.ts

import { Taapit } from "taapit-sdk";
import { cookies } from "next/headers";

const taapit = new Taapit({
  apiKey: process.env.TAAPIT_API_KEY,
});

export async function POST(request: Request) {
  const body = await request.json();

  // Get tracking ID from cookie
  const cookieStore = cookies();
  const trackingId = cookieStore.get("ta_tid")?.value;

  // Create user in your database
  const user = await db.users.create({
    email: body.email,
    name: body.name,
  });

  // Track the lead
  if (trackingId) {
    await taapit.track.lead({
      trackingId,
      customer: {
        externalId: user.id,
        email: user.email,
      },
    });
  }

  return Response.json({ user });
}

Step 1: Frontend - Add the script

<script src="https://taap.it/api/sdk"></script>

Step 2: Frontend - Send tracking ID to backend

<script>
  document
    .getElementById("signup-form")
    .addEventListener("submit", async (e) => {
      e.preventDefault();
      const formData = new FormData(e.target);

      // Include tracking ID in request
      await fetch("/api/signup", {
        method: "POST",
        headers: { "Content-Type": "application/json" },
        body: JSON.stringify({
          email: formData.get("email"),
          name: formData.get("name"),
          trackingId: taapit.getTrackingId(), // Include this!
        }),
      });
    });
</script>

Step 3: Backend - Call the REST API

curl -X POST https://track.taap.it/api/events/lead \
  -H "Authorization: Bearer taapit_sk_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "trackingId": "rLnWe1uz9t282v7g",
    "customer": {
      "externalId": "user_123",
      "email": "[email protected]"
    }
  }'

Track a Sale

trackingId for sales: If the customer was already tracked via a lead event, the trackingId is optional for sale events. You only need to provide the customerExternalId to link the sale to the existing customer. If this is a new customer (no prior lead), trackingId is required.

Node.js SDK
REST API

export async function POST(request: Request) {
  const body = await request.json();
  const cookieStore = cookies();
  const trackingId = cookieStore.get('ta_tid')?.value || body.trackingId;
  
  // Verify payment
  const order = await verifyPayment(body);
  
  // Track sale
  // trackingId is optional if customer was already tracked via a lead event
  await taapit.track.sale({
    trackingId, // Optional if customer already exists
    customer: {
      externalId: order.userId, // Required - links to existing customer or creates new one
      email: order.customerEmail,
    },
    amount: order.total,      // e.g., 149.99 (NOT cents)
    currency: order.currency, // e.g., 'eur'
    metadata: {
      orderId: order.id,
      productIds: order.items.map(i => i.productId),
    },
  });
  
  return Response.json({ success: true });
}

# With trackingId (new customer or first-time tracking)
curl -X POST https://track.taap.it/api/events/sale \
  -H "Authorization: Bearer taapit_sk_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "trackingId": "rLnWe1uz9t282v7g",
    "customer": {
      "externalId": "user_123",
      "email": "[email protected]"
    },
    "amount": 99.99,
    "currency": "eur",
    "metadata": {
      "orderId": "order_456"
    }
  }'

# Without trackingId (customer already tracked via lead event)

curl -X POST https://track.taap.it/api/events/sale \
 -H "Authorization: Bearer taapit_sk_xxx" \
 -H "Content-Type: application/json" \
 -d '{
"customer": {
"externalId": "user_123"
},
"amount": 99.99,
"currency": "eur"
}'

The amount must be in currency units, not cents.

✅ amount: 29.99 for €29.99
❌ amount: 2999 (this would be €2999)

Request Body

{
  "trackingId": "rLnWe1uz9t282v7g",
  "customer": {
    "externalId": "user_123",
    "email": "[email protected]",
    "firstname": "John",
    "lastname": "Doe",
    "phoneNumber": "+33612345678",
    "avatarUrl": "https://example.com/avatar.jpg"
  },
  "amount": 99.99,       // Sale only
  "currency": "eur",     // Sale only
  "metadata": {}
}

Field	Type	Required	Description
`trackingId`	string	See below	The `ta_tid` from cookie/URL
`customer.externalId`	string	Yes	Your internal user ID
`customer.email`	string	No	User’s email
`amount`	number	Sale only	Amount in currency units
`currency`	string	Sale only	ISO 4217 code (eur, usd…)
`metadata`	object	No	Custom data

When is trackingId required? - Lead events: trackingId is always required - Sale events: - If the customerExternalId was already tracked (via a previous lead event), trackingId is optional - If this is a new customer (no prior lead event), trackingId is required to create the customer record

Response

{ "ok": true }

Best Practices

1. Get tracking ID from multiple sources

const cookieStore = cookies();
const trackingId =
  cookieStore.get("ta_tid")?.value || // Cookie (preferred)
  body.trackingId || // Request body
  new URL(request.url).searchParams.get("ta_tid"); // URL param

2. Always track after confirmation

// ✅ Good - Track after payment is confirmed
const paymentResult = await processPayment();
if (paymentResult.success) {
  await taapit.track.sale({...});
}

// ❌ Bad - Track before confirmation
await taapit.track.sale({...});
const paymentResult = await processPayment(); // Might fail!

3. Store tracking ID for later use

// When creating checkout session
const session = await stripe.checkout.sessions.create({
  metadata: { ta_tid: trackingId }, // Store for webhook
});

// Later in webhook, retrieve it
const trackingId = session.metadata.ta_tid;

4. Log tracking failures

const result = await taapit.track.sale({...});
if (!result.success) {
  console.error('Taapit tracking failed:', result.error);
  // Don't fail the main operation - tracking is secondary
}
