Error codes

Common error codes from Klarna

• 400 – Bad Value: purchase_currency
  Your account at Klarna doesn’t seem to be configured for the currency used in your store. What currency did you select when you signed up with Klarna? If you need support, you should email your region’s Klarna Merchant contact.
• 401 – Unauthorized
  If you receive this error message, it usually means that you are using your credentials for the wrong plugin. It could also mean that the username and/or password is incorrect. Try copying and pasting instead of typing in directly and double-check for whitespace. If you need support, you should email your region’s Klarna Merchant contact.
• 403 – Invalid_Operations
  A 403 error code means the Klarna credentials authenticate successfully (so Klarna API credentials/username and password are correct), but you haven’t selected the Klarna products to enable these credentials to work yet. This can also occur even when you should be able to select products in the Klarna Merchant Portal. If you need support, you should email your region’s Klarna Merchant contact.
• 403 – Merchant_Inactive
  This means that your Klarna credentials are not activated. If you need support, you should email your region’s Klarna Merchant contact.
• 404 – Not Found
  This can happen when credentials were changed during the order. Please make sure to start a new browser session after changing credentials. If you need support, you should email your region’s Klarna Merchant contact.
• 405 – Method Not Allowed
  Merchants are encountering issues when their Klarna credentials (username and password) are valid, but aren’t correctly configured for the market they are using them for. This should be checked with your region’s Klarna Merchant contact.
• 500 – Internal Server Error
  A 5xx error usually indicates a server-side issue. It could be caused by server configuration problems or a fatal error in plugin or theme code. Contact your hosting provider or developer to investigate.
