The integration is not working. What should I do?

If your integration is not working, start by checking the following:

  • The test mode is switched off
  • Klarna API credentials are entered in the correct place in your plug-in
  • You have the correct version of the Klarna plug-in installed

If you can’t see Klarna’s iframe, it might be due to:

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