With SmartPay 2.0 we unified the modification API and transaction status API responses, to always provide you with the latest transaction information and the full transaction status history in the same model.
Error exposing disclamer
Technical error codes or other details of why a request could not be completed, must not be disclosed to an end user directly, as this might increase the risk of fraudulent activity.
Especially when it comes to credit card fraud, fraudsters often target websites that give a different response to different types of declination (e.g. where one response is returned for the amount exceeding the available credit and another where a card is flagged as stolen).

reconciliationReferenceId:
Within SmartPay, each order on your side is represented by one checkout transactionID. You may use this transactionID to perform the initial checkout, retrieve an overall status or for later modifications, like manual capture or refunds.
On the payment side, this may lead to multiple financial transactions, e.g., one payment transaction about the captuered amount - which will be settled to your account - and later a refund transaction - which will be debited from your account / deducted from your payout.
The reconciliationReferenceId has been introduced to allow you to keep track of those financial transactions, as it represents the financial transactionID, as you would see it in the payment provider's merchant portal (e.g. our merchant panel) or settlement files.
Transaction overview object is returning you basic information of the transaction including the payment option type, as chosen by the consumer.

}Payment provider errors are critical issues which changes the paymentStatus to "FAILED" (e.g., card issuer rejected the transaction due to risk checks). In such cases the transaction cannot be further processed. "FAILED" status for modifications means that only the modification failed, but the transaction might be processed further.
In both cases please log those errors and contact our customer support for further guidance.
