When a student registers or pays on your landing page, Meta receives a browser-side event. When this CRM syncs that data, it sends a server-side event.

By passing the exact same Event ID (e.g. the Razorpay Payment ID or a generated UUID) in both events, Meta will automatically deduplicate them.

Add a hidden field event_id in your Google Form. When the page loads, generate a unique ID, set it in the hidden field, and fire the Pixel:

// 1. Generate unique ID
var eventId = "lead_" + Date.now() + "_" + Math.random().toString(36).substr(2, 5);
document.getElementById("hidden_event_id").value = eventId;

// 2. Fire Browser Pixel
fbq('track', 'Lead', {}, { eventID: eventId });
                                

Configure your Razorpay payment page redirect URL to your thank-you page: https://akanshaacademy.in/thanks-199/. Razorpay will automatically append the razorpay_payment_id.

Extract it on the thank-you page and pass it to the Pixel:

var urlParams = new URLSearchParams(window.location.search);
var payId = urlParams.get('razorpay_payment_id');

if (payId) {
  // Fire Pixel Purchase with payment ID as eventID
  fbq('track', 'Purchase', {
    value: 199.00,
    currency: 'INR'
  }, {
    eventID: payId
  });
}
