Recon Reference extraction
ReconReference extraction setting is only available for the Nedbank https://distributor.an/ 8 digit ReconReference is sent from iVeri to the acquirer to uniquely identify a transaction. This number is used to query transaction information with the acquirer, and it may appear on the merchant reconciliation statement. By default, a ReconReference is generated by the iVeri Gateway. A merchant has the option for their ReconReference to be derived from their MerchantReference. Since a MerchantReference can be in free text format of up to 64 characters, various rules determine how the 7-digit ReconReference is derived from extracting a section of the Merchant Reference. The configuration for activating a derived ReconReference requires:

  • fixed starting position
  • maximum length of up to 7 digits (first digit reserved as a control digit)
  • direction: left-to-right or right-to-left.

Transaction Type repetition within transaction sequence

Auhorisations, AuthorisationReversals, Debits and Credits are by default limited to one successful of each type per transaction sequence. An ApplicationID can be configured to not limit the successful count of any of these within a transaction sequence. A MerchantTrace must be supplied for transactions using an ApplicationID with this configuration activated.


AuthorisationReversals and Debits reduce the authorisation amount available (for subsequent authorisations, authorisation reversals and debits). Similarly, Credits reduce the total amount debited.


The possible Advanced transaction sequence flow with an initial Authorisation is the following:
The possible Advanced transaction sequence flow with an initial Debit is the following:
The possible Advanced transaction sequence flow with an initial Credit is unchanged from the diagram shown within the “Sequence” section (6.5).
