feat(BTI-584): update Klarna MOR to DataRequestKey flow#11
Merged
Conversation
Klarna no longer returns a reservation number; follow-up actions reference the prior Reserve through the Buckaroo DataRequestKey service parameter. - Fix cancelReservation to post to /json/DataRequest with DataRequestKey (was posting to /json/transaction with OriginalTransactionKey) - Add updateReservation and extendReservation DataRequest actions - Align allowed service parameters and required_fields per action with the BPS Klarna docs (operatingCountry mandatory on Reserve; Pay requires an invoice) - Remove AddShippingInfo: the gateway rejects it for the klarna service (ActionUnknown); shipping details ride on the Pay request instead - Refund keeps the base OriginalTransactionKey path Verified end-to-end against the Buckaroo test gateway: Reserve -> hosted-page approval -> ExtendReservation -> Pay (captured) -> Refund all succeed.

What
Updates the existing Klarna MOR (
klarna) builder to the new BPS spec: Klarna no longer returns a reservation number, so every follow-up references the prior Reserve through the Buckaroo DataRequestKey (a service parameter), posted to/json/DataRequest.Changes
cancelReservation— was posting to/json/transactionwithOriginalTransactionKey; now posts to/json/DataRequestwithDataRequestKey, per docs.updateReservationandextendReservationDataRequest actions.required_fieldsper action with the BPS Klarna docs:operatingCountrymandatory on Reserve, billing/shipping optional; Pay requires an invoice.klarnaservice (Unknown action 'AddShippingInfo'). Shipping details ride on the Pay request (shippingMethod/company/trackingNumber), matching the up-to-date docs. Note: BTI-584 lists AddShippingInfo, but it does not exist for this service.OriginalTransactionKeypath.Verification
