Response

The /{API_version}/Payment/Start endpoint returns a JSON object with the following properties.

PaymentId

The Barion server generated guid for the payment that the request initialized.

PaymentRequestId

The Barion shop’s unique string identifier for the payment that was passed as PaymentRequestId in the request.

Status

The payment’s current status within Barion: one of the string values in the PaymentStatus enumeration.

QRUrl

A URL to a QR code that represents the payment.

RecurrenceResult

String status of the tokenization or the subsequent charge to a tokenized payment instrument: “None”, “Failed”, “Successful”, “NotFound”, or “ThreeDSAuthenticationRequired”.

For details, see the dedicated section.

Always returned, but only applies to payments that are part of a tokenized payment scenario

How to interpret RecurrenceResult

Value Description
None Either the payment isn’t part of a token payment scenario, or, if InitiateRecurrence: true (and no RecurrenceId) was passed in the request, the tokenization was successful, but no attempt has been made to use the token.
Successful InitiateRecurrence: false and a RecurrenceId was passed in the request, and the previously tokenized payment instrument has been successfully used to complete the payment.
Failed InitiateRecurrence: false and a RecurrenceId was passed in the request, but the previously tokenized payment instrument couldn’t be charge to complete the payment.
NotFound The RecurrenceId passed in the request is invalid, or the previous tokenization had been unsuccessful.
ThreeDSAuthenticationRequired InitiateRecurrence: false and a RecurrenceId was passed in the request, but the payment didn’t go through because The holder of the card whose token you registered is challenged to perform 3-D Secure authentication.
Perform off-site 3-DS authentication, or pass the TraceId associated with the payment instrument in the request.

Transactions

All the transactions associated with the payment: an array of ProcessedTransaction object

Includes all applicable Barion-deducted fees.

GatewayUrl

The URL of the Barion Smart Gateway where the payer needs to be redirected for payment.

Includes the PaymentId as a query string.

CallbackUrl

The URL where the Barion server sends a request each time there is a change in the payment’s status.

Includes the PaymentId as a query string.

If no CallbackURL was passed in the request, this property defaults to the URL of the Barion shop whose POSkey was passed.

RedirectUrl

The URL where the payer is redirected once they complete the payment. Includes the PaymentId as a query string.

If no RedirectURL was passed in the request, this property defaults to the URL of the Barion shop whose POSkey was passed.

ThreeDSAuthClientData

Encrypted client authentication data, as a string, required for 3-D Secure processing.

Pass this data to the off-site authentication library if a token payment was rejected because of missing authentication.

TraceId

A unique string identifier generated by the card issuer to represent and track the payment instrument in token payment scenarios that require 3-D Secure authentication.
