Name Description
AdditionalData Additional data you pass with the tender. The additionalData object is a generic container that can hold extra response fields. The system uses the card number as a key to collect relevant additional data, for example loyalty data or recurring contract information.

Additional data elements

When the additional data callback is triggered the cash register is provided with a large number of data elements which can be used in business processes to make decisions on the progress of the transaction. This is typically used for loyalty as the most distinguishing information concerns the cardholder-specific information. An example list contains the following:

shopperReference YOUR_UNIQUE_SHOPPER_ID_IOfW3k9G2PvXFu2j
stored_value_redemption_type Perform a cash back or deactivate a card by passing a stored value redemption type in additional data. 
  • cashback - Cash out the value of a gift card. For SVS, you must create a zero-value transaction to cash out the entire balance of a card. You can not cash out a specific amount.
  • deactivate (not available for SVS) - Deactivates a gift card.  (Deactivate is not available for SVS).

  • gratuity (SVS cards only) - Used to provide a tip from a gift card. (For SVS cards only).

The cashback and deactivate values can be piped to chain the tasks by passing "cashback|deactivate".

All these elements are present for chip-based transactions while several are non-existent for MSR or NFC transactions. Non-existence should not block the cash register from standard operating. Additional elements may be present depending on the transaction options like Gratuity.
