Klarna Payment Process

When users submit your form, they will be redirected to Klarna’s payment page to complete the payment process. Here’s a demo:


  • The payment completion might take up to 10 minutes. In this case, you will find the payment from the Incomplete Payment section of the Jotform Tables.
  • If you complete a payment from the Incomplete Payment section, you won’t see the Transaction ID in form emails, Jotform Tables, and Inbox even after you receive the payment. In this case, we recommend waiting for the payment to complete.
  • Manually completed submissions in forms integrated with Klarna will always increase your payment submission count, even if they are in test mode.

Viewing Payments with Klarna

At Klarna, you can view the transactions under the Bank Transfer section. Here’s how you can do that:

  1. Go to the Bank Transfer section of your Klarna dashboard.
  2. Scroll down and look for the payment made through your form.
  3. Click the Transaction ID to view the full payment details, including the Form ID and Submission ID.
