on behalf of the customer. You must persist this token in your system associated with the customer
account. To de-duplicate customers, you should use the `customer_id` as the unique identifier.


Partner reference to the customer token created on Klarna side.
This will be exposed in webhooks related to changes to the customer token (e.g. token revoked) for the purpose of correlating your resource with the Klarna customer token.

The One Klarna Token represents a customer's consent, allowing a merchant to charge their Klarna account
or enabling Klarna to charge the customer's payment method or funding source without the customer being
physically present.


The SDK token can be used when initializing Web SDK or Mobile SDK in order to personalize customer experience.


An unexpected error occurred in the API.

The request may be retried without modification after a delay.

If this error persists, please reach out to your Klarna support contact.

The request may be retried without modification after a delay.


HMAC-SHA256 signature over the HTTP request body signed with the key identified by `Klarna-Signing-Key-ID`. 

The signature is calculated over the full HTTP request body.

  `computedHexDigest = HMAC_SHA256_HexDigest(request.body, getSecretKey(request.headers["Klarna-Signing-Key-ID"]))`

Compare the computed signature with the value of the `Klarna-Signature` header. If they match, the request is coming
from Klarna and you can process the webhook. If they do not match, you should reject the request.


The unique identifier of the delivered event.

A boolean flag indicating whether the event is generated in a production environment.

The timestamp when the event occurred. In ISO 8601 with timezone e.g. 2024-01-01T12:00:00Z


The unique identifier of the product instance.
