Connect Klarna

TackQuote's Klarna integration lets buyers settle a quote with Klarna's pay-later and instalment options instead of paying the full amount up front, which can shorten the decision on larger orders. TackQuote creates a Klarna payment session and wraps it in a Hosted Payment Page, so Klarna handles the buyer's eligibility and payment flow entirely. Checkouts are created with automatic capture enabled, because a quote has no shipment step to trigger a later capture — and settlement is confirmed by reading the captured amount back from Klarna Order Management, not by trusting the status callback.

TackQuote connects to Klarna with API credentials plus your account region. The callback URL is registered automatically at checkout, so there is nothing to paste into Klarna.

• Klarna merchant account with the products you want to offer enabled
• Klarna API username and password
• Your Klarna account region (Europe, North America or Oceania)
• A verification token you generate — Klarna does not sign its status callbacks
• TackQuote Starter plan or above

1. 1

   Get Klarna API credentials

   In the Klarna Merchant Portal go to Settings → Klarna API credentials and generate an API username and password.
2. 2

   Note your account region

   Klarna serves Europe, North America and Oceania from separate hosts, and credentials only work against their own region. TackQuote asks for this because it cannot be detected from the key.
3. 3

   Connect in TackQuote

   Enter the username, password, region and a long random verification token in Settings → Payments → Klarna.
4. 4

   Go live

   The buyer starting checkout is what routes a quote to Klarna, and only when no higher-priority gateway (Stripe, Authorize.net, Square, Adyen, PayPal, Razorpay, Mollie) is connected. Captured orders convert the quote once the amount and currency match.
