How to track sales from PayPal

AT A GLANCE

With PayPal, NEMO tracks which link brings each sale with no pixels and no Google Analytics. Know which link or video brought you each PayPal payment — with Auto Return to your thank-you page. PayPal can send the buyer back to a page of yours when the payment is done. There, the NEMO script recognizes their source and records the sale. The method is “The thank-you page” (thank-you page · good reliability): After paying, the buyer lands on a page of yours with the NEMO script: the sale is recorded there with its source (the 90-day cookie). It depends on the purchase happening in the same browser as the click. The return URL is ONE for the whole PayPal account: use a generic thank-you page that works for all your products. The full connection is 3 steps and you verify it with a single test click.

How is each PayPal sale attributed?

The thank-you page · Thank-you page · good reliability

PayPal can send the buyer back to a page of yours when the payment is done. There, the NEMO script recognizes their source and records the sale.

1. Point your NEMO link at YOUR sales page (the one with the PayPal button).
2. Create your thank-you page (same domain) and paste this:

   <script src="https://nemolink.app/nemo.js" defer></script>
   <script>
     document.addEventListener("DOMContentLoaded", function () {
       if (window.nemo) window.nemo.track("sale", {
         event_name: "Purchase",
         amount_cents: 4900 // €49.00 — change it or remove the line
       });
     });
   </script>

3. In PayPal: Account Settings → Website payments → “Website preferences” → Update → turn on “Auto return” and paste your thank-you page URL. Save. Open Website preferences in PayPal

Note: The return URL is ONE for the whole PayPal account: use a generic thank-you page that works for all your products.

Note: If someone pays as a guest (no PayPal account), they may not be redirected automatically and will have to click “Return to Merchant” — the sale is recorded all the same if they do. To cover every case, the purchase tag in your email platform is the safety net.

Note: Does your automation tool (Zapier, Make, n8n…) see these sales? Then you can also notify them server-side with the “Sales webhook” card in this catalog — one POST and it's attributed.

Note: PayPal's payment notices carry neither the source nor the buyer's email, so attribution with PayPal goes through your page: this guide's Auto Return — and the “Sales webhook” if you use Zapier, Make or n8n.

Check it in one minute

1. Click your own NEMO link.
2. Open your thank-you page directly in the same tab.
3. The test sale shows up attributed in your NEMO dashboard.

Frequently asked questions

What do I do if payments come in but the sale doesn't show up in NEMO?

Did the buyer pay as a guest and close without coming back to your site? That's PayPal's known return limitation. Cover it with the purchase tag in your email platform — it counts the sale even if nobody returns to your page.

What do I do if payPal won't let me turn on Auto return?

You need a Business account. And the URL must start with https://.

What do I do if the sale arrives “no source”?

The buyer didn't pass through your page with the script before paying (or used another browser). Your NEMO link must land on your sales page.
