Inquiry

Cortina DQR uses the Inquiry to inquire the approval status of a Transaction ID. This call will include the transaction’s final amount and the transaction ID generated in the GenerateQR call.
An “Approved” response this call will usually attempt to vend/release the product.
A “Decline” will terminate the transaction and a “Pending” response will trigger a subsequent Inquiry request after a predefined time. The Cortina payment provider shall validate the information and respond with the Dynamic QR information to be displayed on the Nayax device accordingly. This command is essential for the duration of the authorization process.

Response

The InquiryResponse that the customer’s payment method would send to Nayax’s servers. Usually the response would be either “Approved” or “Declined” with code 993 which means “pending”- meaning the payment provider is still working on deciding on whether or not to approve the consumer (pending “Approved” or “Declined” response).
In case of “pending” response, it will lead to Nayax’s servers to keep polling until either a final response have been received (“Approved”/Declined”) or it reaches the limit as configured in Nayax Core. The payload should look as follows:

{
  "Status": {
    "Verdict": "Approved",
    "Code": 0,
    "StatusMessage": "Cortina V2 Stub Tester"
  },
  "PaymentInfo": {
    "AuthCode": "333333",
    "AuthAmount": 0.1,
    "SettAmount": 0.1,
    "Token": "Cortina V2 Stub Tester Token",
    "AuthDateTime": "230221101008",
    "SettDateTime": "230221101009",
    "TraceNumber": "4444",
    "AuthSource": "555555",
    "AdditionalData": ""
  }
}
