This guide wires the whole loop together for a Stripe-powered SaaS: tracking links, the pixel, a read-only Stripe connection, and the one line at checkout that makes attribution exact. Budget about 15 minutes. Go to **Campaigns → New campaign**, set your destination (e.g. your pricing page), and tick the channels you'll share it on. TrackRev mints one link per channel with UTMs baked in. Full details: [Create links](/link-tracking/create-links). Add the snippet to the `` of every page — marketing site *and* app: ```html theme={null} ``` Then click **Check pixel** on the Integrations tab. See [Install the pixel](/getting-started/install-pixel). Call `identify()` on sign-up or login so an email is tied to the visitor (this is the fallback that catches sales without a checkout reference): ```js theme={null} window.trk?.identify("customer@example.com"); ``` On **Integrations → Connect your revenue provider**, choose **Stripe** and use **Quick connect** to create a restricted key with the pre-selected read scopes (include `rak_webhook_write` for instant sync). Paste the `rk_…` key. See [Connect Stripe](/revenue-attribution/connect-stripe). Set the visitor id on the Checkout Session so the sale joins to the click exactly: ```js theme={null} const vid = (await cookies()).get("vid")?.value; const session = await stripe.checkout.sessions.create({ mode: "subscription", line_items: [/* ... */], success_url: "https://yourapp.com/thanks", client_reference_id: vid, // ← the join key }); ``` More options (Payment Links, Pricing Table) in [Pass the visitor id to checkout](/revenue-attribution/pass-vid-to-checkout). On **Integrations → Verify your checkout setup**, click **Check attribution setup**. Aim for an **OK** — it confirms a `vid` is present and matches a tracked visitor. Click one of your links, complete a (test-mode) purchase passing the `vid`, and wait for the sync (hourly, or seconds with the webhook). The order appears under **Orders**, and **Channels** credits it to the right channel. On **Attribution**, pick last-touch, first-touch or linear and set your window (default 30 days). See [Attribution models](/revenue-attribution/attribution-models). You now have every Stripe sale credited to the channel that earned it — and lifetime value by channel building as subscriptions renew. ## Troubleshooting The `vid` isn't reaching Stripe. Confirm the pixel is on the page checkout starts from, and that you pass `client_reference_id: window.trk.vid`. Email matching only works if you also called `identify(email)`. Check the Stripe key is valid (the verifier reports `error` if it's revoked or missing a scope), and click **Sync now**. First sync looks back 30 days. Revenue attribution is a paid feature — upgrade from the Free tier to reveal it. See [Plans & billing](/account/plans-and-billing).
