Conversion tracking for Klarna
Buy-now-pay-later is the payment method most likely to break a store's conversion tracking, and almost nobody notices because it looks like a small percentage until you measure it. The customer leaves your site for Klarna's approval flow, and a meaningful share never come back to your confirmation page — the order exists, the money is committed, and no pixel fired. On top of that, Klarna orders can be authorized and then captured later, so the moment you count the sale is a decision rather than an obvious fact.

Klarna tracking · what breaks
What goes wrong on Klarna
- 01
The customer redirects away and does not return
Klarna approves, the order is placed, and the confirmation page never loads. The sale is real and the conversion does not exist.
- 02
Authorization and capture are separate moments
Counting at authorization risks orders that never capture; counting at capture delays the signal.
- 03
Klarna orders under-reported and blamed on the campaign
The channels that skew toward BNPL users look worse than they are.
- 04
Returns higher on BNPL
Pay-later carts return at a higher rate in many stores, and unreversed returns overstate revenue.
Klarna tracking · the fix
What changes — Klarna tracking
Orders sent from the store's own record
Server-side, so the redirect stops mattering.
A deliberate decision on authorization versus capture
Written down, so the number means one thing.
Returns reversed
Which matters more here than on card orders.
Klarna tracking · architecture
What Klarna actually lets you do
What the Klarna integration gives you, and what it takes away.
- 1
An order in your own store regardless of the redirect
Which is why the store's order record, not the browser, is the reliable source.
- 2
Separate authorization and capture states
Real and meaningful, and a decision you have to make explicitly.
- 3
Klarna's own settlement reporting
Authoritative for what Klarna paid you, which is net of their fee.
- 4
A hosted approval flow
On Klarna's domain, so nothing you set in a cookie follows the customer there.
- 5
No conversion sending of its own
Klarna is a payment method, not a measurement tool.
Klarna tracking · diagnose
Where Klarna tracking breaks, in diagnostic order
Each check rules out a class of cause, so by the last one there is usually a single explanation standing.
- 01
Count Klarna checkouts started against confirmation pages loaded
The gap is the share of BNPL orders your browser-side setup cannot see.
- 02
Check whether the conversion fires from the order or the page
If it is the page, you have found the cause.
- 03
Compare store orders paid with Klarna against reported conversions
Per order, for a closed window.
- 04
Check whether the return rate on BNPL differs
In most stores it does, and unreversed returns then overstate BNPL revenue specifically.
- 05
Confirm no double counting for customers who did return
Both the page tag and the server event may fire.

The QA evidence — Klarna tracking
Run on Klarna specifically, on a live conversion rather than in preview mode.

Klarna tracking · when not to buy
When you don't need this on Klarna
Worth reading before you buy anything, from us or anyone.
- If Klarna is a very small share of your orders, measure the share before commissioning anything — it may not move a decision.
- If your conversions already fire from the order record rather than the confirmation page, this is largely working.
- The checkouts-started against confirmations-loaded count is free and takes ten minutes. Do it first.
- If your BNPL provider is different, the same shape applies — the redirect is the problem, not the brand.

FAQ
Klarna tracking questions, answered
Because the customer leaves your site for the provider's approval flow and a meaningful share never come back to your confirmation page. The order was placed and the money committed, but a pixel that fires on page load never ran. Count the checkouts started against the confirmation pages loaded and you will see the size of it in ten minutes.
Either, deliberately. Authorization is immediate and includes a small number of orders that never capture; capture is accurate and delays the signal until fulfilment. Most stores are better served by authorization plus a reversal for the ones that fail, because bidding benefits from the faster signal.
Yes. The redirect is the problem, not the brand. Any pay-later provider that takes the customer to its own domain for approval creates the same gap, and the same server-side fix closes it.
Because BNPL carts return at a higher rate in many stores — the payment method lowers the commitment at purchase. If returns are not reversed, BNPL revenue is overstated by more than card revenue is, which makes the channels that drive it look better than they are.
