Payment Processing

async function handlePurchase() {
  const response = await fetch('/api/create-checkout-session', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      priceId: 'price_XXXXXXXXXXXXXXXX',
      successUrl: window.location.origin + '/thank-you',
      cancelUrl: window.location.origin + '/offer'
    })
  });
  const { url } = await response.json();
  window.location.href = url;
}

Stripe Payment Link (No-Code)

<a href="https://buy.stripe.com/XXXXXX" class="cta-primary">
  Buy Now — $297
</a>

CRM Integration

HubSpot Form

<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/v2.js"></script>
<script>
  hbspt.forms.create({
    region: "na1",
    portalId: "YOUR_PORTAL_ID",
    formId: "YOUR_FORM_ID",
    target: "#hubspot-form"
  });
</script>
<div id="hubspot-form"></div>

Webhook Integration (Universal)

For any tool that supports webhooks:

// Send form data to a webhook
document.querySelector('form').addEventListener('submit', async (e) => {
  e.preventDefault();
  const formData = new FormData(e.target);
  const data = Object.fromEntries(formData);

  await fetch('https://hooks.your-automation.com/webhook/XXXX', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(data)
  });

  window.location.href = '/thank-you';
});
