When it comes to conversion tracking, a sale event happens when a user purchases your product or service. Examples include:
  • Subscribing to a paid plan
  • Usage expansion (upgrading from one plan to another)
  • Purchasing a product from your online store
A diagram showing how lead events are tracked in the conversion funnel
In this guide, we will be focusing on tracking sales conversion events without a prior lead event. This is useful when you want to attribute a sale directly to a click, bypassing the lead tracking step.

​
When to use direct sale tracking

Direct sale tracking is ideal for scenarios where:
  • You don’t need to track leads separately (e.g., one-time purchases)
  • You want to attribute sales directly to clicks without intermediate steps
  • You’re tracking sales for users who haven’t signed up or created an account
If you’re tracking both leads and sales in your conversion funnel, refer to our server-side tracking or client-side tracking guides instead.
Lead commission rewards will not be created when using direct sale tracking.

​
Prerequisites

First, you’ll need to enable conversion tracking for your Dub links to be able to start tracking conversions:
If you’re using Dub Partners, you can skip this step since partner links will have conversion tracking enabled by default.
To enable conversion tracking for all future links in a workspace, you can do the following: To enable conversion tracking for all future links in a workspace, you can do the following:
  1. Navigate to your workspace’s Tracking settings page.
  2. Toggle the Workspace-level Conversion Tracking switch to enable conversion tracking for the workspace.
Enabling conversion tracking for a workspace
This option will enable conversion tracking in the Dub Link Builder for all future links.
Alternatively, you can also enable conversion tracking programmatically via the Dub API. All you need to do is pass trackConversion: true when creating or updating a link:
const link = await dub.links.create({
  url: "https://dub.co",
  trackConversion: true,
});

link = d.links.create(url="https://dub.co", track_conversion=True)

link, err := d.Links.Create(ctx, &dub.CreateLinkRequest{
    URL: "https://dub.co",
    TrackConversion: true,
})

s.links.create_many(
  ::OpenApiSDK::Operations::CreateLinkRequest.new(
    url: "https://dub.co",
    track_conversion: true,
  )
)
Then, you’ll need to install the Dub Analytics script and set up the necessary configuration for client-side conversion tracking:
1

Allowlist your site's domain

Then, you’ll need to allowlist your site’s domain to allow the client-side conversion events to be ingested by Dub.To do that, navigate to your workspace’s Tracking settings page and add your site’s domain to the Allowed Hostnames list.This provides an additional layer of security by ensuring only authorized domains can track conversions using your publishable key.
Enabling conversion tracking for a workspace
You can group your hostnames when adding them to the allow list:
  • example.com: Tracks traffic only from example.com.
  • *.example.com: Tracks traffic from all subdomains of example.com, but not from example.com itself.
When testing things out locally, you can add localhost to the Allowed Hostnames list temporarily. This will allow local events to be ingested by Dub. Don’t forget to remove it once you’re ready to go live!
2

Generate your publishable key

Before you can track conversions on the client-side, you need to generate a publishable key from your Dub workspace.To do that, navigate to your workspace’s Tracking settings page and generate a new publishable key under the Publishable Key section.

3

Install Dub Analytics script

Next, install the Dub Analytics script on your website/web application.You can install the Dub Analytics script in several different ways:

React

Manual installation

Framer

Shopify

WordPress

Webflow

Google Tag Manager

You must configure the publishable key you generated in step 1 when installing the analytics script. Without this key, client-side conversion tracking will not work.
<script>
  !(function (c, n) {
    c[n] =
      c[n] ||
      function () {
        (c[n].q = c[n].q || []).push(arguments);
      };
    ["trackClick", "trackLead", "trackSale"].forEach(
      (t) => (c[n][t] = (...a) => c[n](t, ...a)),
    );
    var s = document.createElement("script");
    s.defer = 1;
    s.src = "https://www.dubcdn.com/analytics/script.conversion-tracking.js";
    s.setAttribute("data-publishable-key", "dub_pk_xxxxxxxx"); // Replace with your publishable key
    document.head.appendChild(s);
  })(window, "dubAnalytics");
</script>

import { Analytics as DubAnalytics } from '@dub/analytics/react';

export default function RootLayout({
  children,
}) {
  return (
    <html lang="en">
      <body className={inter.className}>{children}</body>
      <DubAnalytics
        ...
        publishableKey="dub_pk_xxxxxxxx" // Replace with your publishable key
      />
    </html>
  );
}

​
Track direct sale conversions

To track a direct sale, you need to pass the clickId parameter along with customer information when tracking the sale event. The clickId can be read from the dub_id cookie that’s automatically set when a user clicks on your Dub link.

​
Track direct sales from URL query parameters

If you redirect users to a confirmation page after a successful purchase, you can track direct sales by reading query parameters from the URL and the dub_id cookie. 
import { useAnalytics } from "@dub/analytics/react";
import { useEffect } from "react";

// Helper function to read cookie
function getCookie(name: string) {
  const value = `; ${document.cookie}`;
  const parts = value.split(`; ${name}=`);
  if (parts.length === 2) return parts.pop()?.split(";").shift();
}

export function OrderConfirmationPage() {
  const { trackSale } = useAnalytics();

  useEffect(() => {
    // Get query parameters from URL
    const params = new URLSearchParams(window.location.search);
    const customerId = params.get("customer_id");
    const amount = params.get("amount");
    const invoiceId = params.get("invoice_id");

    // Get click ID from cookie
    const clickId = getCookie("dub_id");

    if (customerId && amount && clickId) {
      // Track the direct sale event
      trackSale({
        eventName: "Purchase",
        customerExternalId: customerId,
        amount: parseInt(amount), // Amount in cents
        invoiceId: invoiceId || undefined,

        // Required for direct sale tracking:
        clickId: clickId,
        customerName: "John Doe", // Optional: customer name
        customerEmail: "john@example.com", // Optional: customer email
        customerAvatar: "https://example.com/avatar.jpg", // Optional: avatar URL
      });
    }
  }, [trackSale]);

  return <div>Thank you for your purchase!</div>;
}

Track direct sales from form submissions

You can also track direct sales when users complete a checkout form on your website. 
import { useAnalytics } from "@dub/analytics/react";
import { useState } from "react";

// Helper function to read cookie
function getCookie(name: string) {
  const value = `; ${document.cookie}`;
  const parts = value.split(`; ${name}=`);
  if (parts.length === 2) return parts.pop()?.split(";").shift();
}

export function CheckoutForm() {
  const { trackSale } = useAnalytics();

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();

    // Get click ID from cookie
    const clickId = getCookie("dub_id");

    if (clickId) {
      // Track the direct sale event
      trackSale({
        eventName: "Purchase",
        customerExternalId: "cus_RBfbD57H",
        amount: 5000, // $50.00
        invoiceId: "in_1MtHbELkdIwH",

        // Required for direct sale tracking:
        clickId: clickId,
        customerName: "John Doe",
        customerEmail: "john@example.com",
        customerAvatar: "https://example.com/avatar.jpg",
      });
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      ...
      <button type="submit">Complete Purchase</button>
    </form>
  );
}

Server-side direct sale tracking

You can also track direct sales from your backend by passing the clickId parameter when calling the track sale API: 
import { Dub } from "dub";

const dub = new Dub();

await dub.track.sale({
  customerExternalId: "cus_RBfbD57HDzPKpduI8elr5qHA",
  amount: 5000,
  paymentProcessor: "stripe",
  eventName: "Purchase",
  invoiceId: "in_1MtHbELkdIwH",
  currency: "usd",

  // Required for direct sale tracking:
  clickId: "cm3w...", // Pass the click ID from your frontend
  customerName: "John Doe",
  customerEmail: "john@example.com",
  customerAvatar: "https://example.com/avatar.jpg",
});

Here are the properties you can include when sending a sale event:
PropertyRequiredDescription
customerExternalIdYesThe unique ID of the customer in your system. Will be used to identify and attribute all future events to this customer.
amountYesThe amount of the sale in cents.
paymentProcessorNoThe payment processor that processed the sale (e.g. Stripe, Shopify). Defaults to “custom”.
eventNameNoThe name of the event. Defaults to “Purchase”.
invoiceIdNoThe invoice ID of the sale. Can be used as a idempotency key – only one sale event can be recorded for a given invoice ID.
currencyNoThe currency of the sale. Defaults to “usd”.
metadataNoAn object containing additional information about the sale.
clickIdNo[For direct sale tracking]: The unique ID of the click that the sale conversion event is attributed to. You can read this value from dub_id cookie.
customerNameNo[For direct sale tracking]: The name of the customer. If not passed, a random name will be generated.
customerEmailNo[For direct sale tracking]: The email address of the customer.
customerAvatarNo[For direct sale tracking]: The avatar URL of the customer.
When to track sale: Track sale events only after a user successfully completes a purchase or payment-related action. Ensure the event is triggered only after the backend confirms the payment was successful.
