Connect Generic Stripe Checkout to Qanary

Time: ~10 minutes. You need: a Qanary program (its slug), your billing provider already connected in Qanary onboarding, and admin access to Generic Stripe Checkout.

1 · Paste the tracking snippet

<script src="https://app.qanary.cloud/qanary.js" data-qanary="YOUR_PROGRAM_SLUG" async></script>

Paste the snippet in your app layout’s .

The snippet sets the first-party attribution cookie when a visitor lands with ?via=AFFILIATE_CODE (the link format your affiliates already share) and records the touchpoint.

2 · Carry the referral into checkout

Server-side, when creating the Checkout Session, set client_reference_id to Qanary.checkoutStamp().ref and metadata.qanary_visitor to stamp.visitor_id. That’s the whole integration — the webhook connection you made during onboarding closes the loop.

3 · Verify

  1. Open your site with ?via=<a promoter code> in a private window.
  2. Run a test-mode checkout.
  3. In Qanary: the conversion appears attributed to that promoter — or ask your coding agent to run the MCP diagnose_attribution tool, which walks visit → identify → webhook → attribution → ledger and tells you exactly where anything is off.
  4. Optional: add a webhook endpoint (Webhooks page) and press Send test event to verify your automation receiver too.
