Klarna API key password length

I have tested the latest version of the module beta-3.0.0 and get the following error message:

An error occurred for order #698: [Klarna\ApiException]: [401] Client error: `POST https://api.klarna.com/payments/v1/sessions` resulted in a `401 Unauthorized` response: @"error_code": "PERMISSION_DENIED", "error_message": "Authentication failed or permission not granted"

I added suggested fix but still get the error.

Can you check if overriding the API key in settings.php works?

Add something like this to your settings.php file, just replace the klarna_payments with the actual ID of your Klarna payment gateway:

$config['commerce_payment.commerce_payment_gateway.klarna_payments']['configuration']['password'] = '123';

Hi,
Unfortunately not.

Error when processing a transaction:
An error occurred for order #709: [Klarna\ApiException]: [401] Client error: `POST https://api.klarna.com/payments/v1/sessions` resulted in a `401 Unauthorized` response: @"error_code": "PERMISSION_DENIED", "error_message": "Authentication failed or permission not granted"

Error when running drush command:
[error] Config commerce_payment.commerce_payment_gateway.klarna_payments does not exist

I have tested with password key in the following formats:
$config['commerce_payment.commerce_payment_gateway.klarna_payments']['configuration']['password']
= '';
$config['commerce_payment.commerce_payment_gateway.klarna_payments']['configuration']['password']
= '';

You need to change the klarna_payments part to match whatever your payment gateway ID is.

You can find it by going to Commerce -> Configuration -> Payment gateways.

It should be the value of "ID" field. In my case it's klarna_payments:

So if your ID were called klarna_something, then the drush command should be:

drush cget commerce_payment.commerce_payment_gateway.klarna_something --include-overridden

And the $config:

$config['commerce_payment.commerce_payment_gateway.klarna_something']['configuration']['password']
= 'apikey';

Got it. Here is the result:

Upon further testing it appears the same error message is shown with the similar Commerce Klarna Checkout module.

"PERMISSION_DENIED", "error_message": "Authentication failed or permission not granted"

Would this indicate that either Klarna has changed their API or i am using the wrong login credentials.

Within the Klarna merchant portal there are three options for integrating:
1.Klarna API keys
2. Client ID with password
3. SMTP authentication

I've tried with all three variants and in the case of #1 - with and without the 'klarna_live_api_' prefix in the password.

I am assuming i should use #1 ...?

Go to Settings -> Klarna API Keys -> click "Generate new Klarna API Key" button and it should give a downloadable text file with "username" and "password".

The password should include the klarna_live_api_ prefix
