Payment Tracking

Automatically detect payments from Stripe, LemonSqueezy, and Polar.

Overview

Revlytics auto-detects payment completions by looking for checkout parameters in the URL when a user returns to your site after a payment.

Supported providers

Provider	Detection	URL Parameter
Stripe	Checkout Session ID	session_id=cs_*
LemonSqueezy	Order ID	order_id=*
Polar	Checkout ID	checkout_id=*

How it works

1. A user completes a purchase on Stripe/LemonSqueezy/Polar
2. They’re redirected back to your site with a checkout parameter in the URL
3. Revlytics detects the parameter and fires a payment event
4. The event is deduplicated per session using sessionStorage — so refreshing the success page doesn’t double-count

Example

If a user returns to https://example.com/success?session_id=cs_live_abc123, Revlytics fires:

{
  "type": "payment",
  "provider": "stripe",
  "stripe_session_id": "cs_live_abc123"
}

No configuration needed

Payment detection is fully automatic. Just make sure your checkout success URL is on the same domain where the Revlytics script is installed.
