My API credentials don’t work. What should I do?
If you have an issue with using API credentials you’ve generated, start trouble-shooting here:
- Check that the test mode is disabled
- Try copy-pasting credentials again (check there are no typos or extra spaces)
- Verify that you’re using the correct integration (we offer 2 integrations – full checkout replacement and Klarna as a payment option within your existing checkout solution; your credentials will only work for the integration you’ve signed up for)
- Ensure you’re not using playground/test credentials when communicating with our live environment or the other way around
