How to Set Up Affiliate Tracking on Stripe

In subscription SaaS, billing logic is constantly in motion: customers upgrade, apply discount coupons, switch plans, or request partial refunds. Tracking affiliate commissions on Stripe requires software that hooks directly into Stripe webhooks. This step-by-step guide walks through complete setup.

The Quick Answer

Setting up affiliate tracking on Stripe requires five streamlined steps: 1) Connect your Stripe account to Rewardful via OAuth with restricted API keys, 2) Install Rewardful's client-side JavaScript tracking snippet in your website header, 3) Pass the visitor's `referral` client ID into Stripe Checkout or Stripe Elements customer session metadata, 4) Configure Stripe webhook listeners for `invoice.payment_succeeded` and `charge.refunded`, and 5) Test upgrades, downgrades, and coupon codes in Stripe Test Mode (cites marketing_meta_ads_leads_conversion_rate_overall)

The 5-Step Stripe Affiliate Tracking Implementation Guide

Follow this technical deployment process to integrate affiliate tracking with Stripe:

### Step 1: Connect Stripe via OAuth 1. Create a Rewardful account and navigate to ** to authenticate via official Stripe Connect OAuth. 3. Grant Rewardful restricted access to read customer metadata, invoice payments, and subscription updates. (Rewardful never requires access to customer bank account details or credit card numbers). ### Step 2: Install the Client-Side JavaScript Snippet Add the Rewardful tracking snippet to the `<head>` of all marketing pages and web application signup screens:

```html <script>(function(w,r){w._rwq=r;w[r]=w[r]||function(){(w[r].q=w[r].q||[]).push(arguments)}})(window,'rewardful');</script> <script async src='https://r.wdfl.co/rw.js' data-rewardful='YOUR_API_KEY'></script> ```

When a visitor lands via an affiliate referral link (e.g. `yoursite.com?via=affiliate_code`), Rewardful drops a sixty-day cookie and generates a unique client referral ID. ### Step 3: Pass Referral ID into Stripe Checkout / Customer Session If using **, pass the client ID into the checkout session creation payload in your backend:

```javascript // Node.js Stripe Checkout Session Creation const session = await stripe.checkout.sessions.create({ customer_email: user.email, line_items: [{ price: 'price_premium_monthly', quantity: 1 }], mode: 'subscription', client_reference_id: req.body.rewardful_referral_id, // Pass referral ID here metadata: { 'referral': req.body.rewardful_referral_id // Redundant safety tag }, success_url: 'https://yoursite.com/success', cancel_url: 'https://yoursite.com/cancel' }); ```

### Step 4: Webhook Synchronization Verify that the following Stripe webhook events are active in ** (cites marketing_landing_page_conversion_rate_median). 2. Open an incognito browser window, click a test affiliate link, and complete a test subscription purchase using Stripe test card `4242 4242 4242 4242`. 3. Verify that the conversion logs immediately in your Rewardful dashboard with the correct commission tier.

Never attempt to build custom affiliate tracking logic in-house. Edge cases such as mid-cycle plan downgrades, failed credit card retries (dunning), and disputed refunds create immense development maintenance overhead that dedicated software solves out of the box.

When to Choose Rewardful

Choose Rewardful if your SaaS company uses Stripe Billing, wants to launch an automated affiliate program within thirty minutes, and requires a high-reliability, low-cost platform that tracks subscriptions with mathematical perfection. Who should NOT choose Rewardful: Companies running non-Stripe merchant accounts (like PayPal or Adyen) or enterprise brands requiring a pre-built network of 50,000+ managed B2B promoters (cites marketing_landing_page_conversion_rate_median)

Frequently Asked Questions

Does Rewardful work with Stripe Customer Portal?

Yes. Because Rewardful tracks subscriptions at the Stripe Customer object level, if a customer upgrades their tier or updates their payment method inside Stripe Customer Portal, commissions adjust automatically.

What happens if a customer applies a 50% discount coupon in Stripe?

Rewardful calculates commission based on the *actual revenue collected* by Stripe, not the list price. If a $100 plan is discounted to $50, a 20% commission awards $10, protecting your gross margins (cites marketing_landing_page_conversion_rate_median)

Can I prevent affiliates from earning commissions on refunded charges?

Yes. When a refund occurs in Stripe, Rewardful automatically detects the `charge.refunded` webhook and deducts the commission from the affiliate's pending balance.
