Processing
The Cancellation service can be performed and processed in three ways:
Offline Cancellation | The Acceptor shall be aware that the transaction was not yet cleared: an AcceptorCancellationAdvice is sent to the Acquirer without an AcceptorCancellationRequest. |
Online Cancellation using the transaction log | The Acceptor perform a search of the transaction log. If the transaction log is found, the Acceptor then asks the Acquirer whether a cancellation can be performed by sending an AcceptorCancellationRequest before sending an AcceptorCancellationAdvice. The AcceptorCancellationRequest may contain some information of the payment transaction to be cancelled. |
Online Cancellation without searching from the log | The Acceptor asks the Acquirer whether a cancellation can be performed by sending an AcceptorCancellationRequest before sending an AcceptorCancellationAdvice. The AcceptorCancellationRequest may contain some information of the payment transaction to be cancelled. |
Configuration

Online Cancellation Reversal An Online Cancellation can be reversed in the same way as an online authorization if:
|
Note |

Cancellation Advice following a Cancellation Request An Online Cancellation Request declined by the acquirer will NOT result in Cancellation advice. See the attached picture below for more information. |
Configuration
Enable Cancellation Service
To enable the Cancellation Service:
Define the Cancellation Service proprieties in the Service Settings Table (E4).
Add the Cancellation Service in the list of configured service in Terminal Data (E1) using:
'DF13' - Configured Services[1, 6] = 1b (Cancellation)
or'DF67' - Configured Services Extended[1, 6] = 1b (Cancellation)
...
Specify which payment services can be cancelled:
To allow the Cancellation of Payment, set
'DF28' - Application Profile Settings(APS) for Cancellation [1, 8] = 1b (Cancellation of Payment)
To allow the Cancellation of Refund, set
'DF28' - Application Profile Settings(APS) for Cancellation [1, 7] = 1b (Cancellation of Refund)
To allow the Cancellation of Pre-Authorization, set
'DF28' - Application Profile Settings(APS) for Cancellation [1, 6] = 1b (Cancellation of Pre-Authorisation)
To allow the Cancellation of Payment Completion, set
'DF28' - Application Profile Settings(APS) for Cancellation [1, 5] = 1b (Cancellation of Payment Completion)
To allow the Cancellation of Cash Advance, set
'DF28' - Application Profile Settings(APS) for Cancellation [1, 4] = 1b (Cancellation of Cash Advance)
Enable Offline Cancellation
Setting Cancellation processing mode (Offline or Online)
The Cancellation Service processing mode is configurable per Application Profile (E6) using the 'DF28' - Application Profile Settings(APS) for Cancellation
.
Offline Cancellation Settings
To enable Offline Cancellation:
Set
'DF28' - Application Profile Settings(APS) for Cancellation [2, 8] = 0b (Cancellation shall be performed offline (without Online Approval Request) for transactions that are neither captured nor reconciled)
.Set
'DF28' - Application Profile Settings(APS) for Cancellation [2, 6] = 0b (Cancellation shall be performed offline (without Online Approval Request) for captured transactions)
.
...
Note |
---|
...
Offline Cancellation |
...
is done through a search in the transaction log. Transaction log Search for Cancellation shall be enabled using |
Online Cancellation Settings
To enable Online Cancellation:
Set
'DF28' - Application Profile Settings(APS) for Cancellation [2, 8] = 1b (Cancellation shall be performed with Online Approval Request for transactions that are neither captured nor reconciled)
.Set
'DF28' - Application Profile Settings(APS) for Cancellation [2, 6] = 1b (Cancellation shall be performed

Online Cancellation using the transaction log
Performing an online cancellation through a search of the transaction log involves the following steps explained below.
Steps Taken for a successful online cancellation:
Terminal Settings ( Tag DF34 byte 3, bit 6 set to 0 , bit 7 set to 1).
...
Ensure that Application Profile Settings for Cancellation (Tag DF28) is configured for the service you want to cancel(byte 1) and is configured to be performed online(byte 2). NOTE: In our case, it is configured online for captured transaction.
Below is an example derived from a cancellation of an original transaction(payment).

PaymentResult result;
result = arkos.doPayment(arkosConfig.AsBytes(), paymentParams.AsBytes()); //In your payment function

Offline Cancellation
Offline cancellations are done through a search in the transaction log as well. Performing an offline cancellation involves the following steps explained below.
Steps Taken for a successful offline cancellation:
Terminal Settings ( Tag DF34 byte 3, bit 6 set to 0 , bit 7 set to 1).
...
Ensure that Application Profile Settings for Cancellation (Tag DF28) is configured for the service you want to cancel(byte 1) and is configured to be performed offline(byte 2). NOTE: In our case, it is configured offline for captured transaction.
Below is an example derived from a cancellation of an original transaction(payment).

result = arkos.doPayment(arkosConfig.AsBytes(), paymentParams.AsBytes()); //In your payment function

Online Cancellation without searching from the log
It is to be noted that a slight modification was made to the flow of the latter (Online Cancellation without searching from the log) to help retrieve some Infos; such as AcquirerID, TerminalID, and etc. As it stands, this seems to be lackluster from Nexofast as they haven't thought out this solution properly. Upon implementing the flow they provided to us (nexoFAST 3.2), we ended up having some issues.
A new function was introduced as a solution to the problem.
The function setSelectedApplicationProfileNumberToDefaultFromServiceEntry
allows us to set a profile, initialized the application, and finally, construct valid messages.
Below is the modified diagram.
...
Steps Taken for a successful online cancellation:
Terminal Settings ( Tag DF34 byte 3, bit 6 set to 1 , bit 7 set to 0).
...
Reference data has been included in the Original Transaction section of CancellationRequest and CancellationAdvice.
Below is an example derived from a cancellation of an original transaction(payment).

Transaction Reversal
An online cancellation can be reversed in the same way as an online authorization during payment if we don't receive any message or if an incident happened after authorization. An online cancellation that received a DECLINED response from the acquirer will NOT result in completion advice.
Below is the obtained cancellation advice XML.

Online Cancellation without searching from the log
It is to be noted that a slight modification was made to the flow of the latter (Online Cancellation without searching from the log) to help retrieve some Infos; such as AcquirerID, TerminalID, and etc. As it stands, this seems to be lackluster from Nexofast as they haven't thought out this solution properly. Upon implementing the flow they provided to us (nexoFAST 3.2), we ended up having some issues.
A new function was introduced as a solution to the problem.
The function setSelectedApplicationProfileNumberToDefaultFromServiceEntry
allows us to set a profile, initialized the application, and finally, construct valid messages.
Below is the modified diagram.
