Klarna Checkout does not work after I have integrated. What is the problem?

Some first steps to go through if your integration does not work:

  • Make sure that test mode is switched off.
  • Make sure that the API-credentials are entered in the correct place in your plugin.
  • Make sure you have the correct version of Klarna’s plugin installed.

    If you can not see Klarnas iframe it might be due to:

  • Klarna’s plugin is not activated.
  • The page with terms and conditions is not linked.
  • Another plugin is disrupting Klarna’s plugin.
  • The design of your webshop, meaning your theme, is not compatible with Klarna’s plugin.
