Step 1: Install JavaScript Snippet
Paste the following JavaScript snippet into the <head> tag:
<script async src='' data-rewardful='80669a'></script>
It must appear on every page of your application and marketing website.
Step 2: Track the conversion on your thank-you page
Execute the rewardful('convert') function immediately after creating the Stripe customer. Usually this occurs somewhere on a thank-you page, an AJAX response handler, or some other callback that fires after your checkout completes.
⚠️ Replace [email protected] with your customer's email address.
It must be the same email address associated with the Stripe customer object.

    This example component shows how you might attach an event handler within componentDidMount() that updates the component's state with the referral UUID:
    import React, { useState, useEffect } from "react";
    const SignupForm = () => {
      const [referral, setReferral] = useState(null);
      // When the component mounts, wire up a callback for when Rewardful is ready.
      // If `window.Rewardful.referral` is present, it means this visitor was referred
      // and we should update state with the referral UUID so it's rendered in the form.
      useEffect(() => {
        window.rewardful('ready', () => {
      }, []);
      // If referral is set, render the referral UUID into a hidden input named "referral".
      return (
          <input type="text" name="customer_name" />
          <input type="email" name="customer_email" />
          { referral ? <input type="hidden" name="referral" value={referral} /> : null }
    When the form data is submitted to your server from React, you then add the referral value to the Stripe customer's metadata:
    // Gather params submitted with <form>
    const customerParams = {
      source: 'tok_visa' // Obtained with stripe.js
    // Add the `referral` parameter from Rewardful to the Stripe customer metadata, if present.
    if (req.body.referral) {
      customerParams.metadata = { referral: req.body.referral }
    // Create the customer in Stripe.
    Adding the referral UUID to the Stripe customer's metadata converts the referral and associates it with the affiliate. Whenever that customer is charged, a commission will be paid to the affiliate according to your campaign rules.
