Purchases completed in the test environment are not processed by our production system and will not result in proper invoices or any fees collected on invoices.

Note: You may not transfer any real personal data to us during testing.

 

Depending on which product you have integrated, we offer a few different triggers:

 

Klarna Checkout test triggers

In our playground (test) environment, you can use any valid address to make a test purchase. You can trigger different behaviour depending on your need. The following options are available:

Desired behaviourConsumer email address pattern
Only present pre-paid optionsexample-email+red@example.com

For example, you could use john.doe+red@abcstore.com as the customer's email address to trigger a checkout that only offers pre-paid payment methods such as card.

Klarna Payments test triggers

The default response from our test environment is positive. You can use various email addresses to trigger different (stateless) behaviour depending on your need. The following options are available:

    • Options are: accept or reject
  • {time delay} the time delay before the decision is made of {status}
