Addendum Data

For some switching paths and acquirers it may be possible to include addendum data which is passed onto the card issuer - this is primarily used for corporate purchasing cards, American Express cards etc.

To include this data with your transactions, the field addendum_data should be added to the request payload with the appropriate data payload for the transaction type - these different payload types are detailed below.

{
  "card_holder": "Jim Smith",
  "card_number": "5123456789012346",
  "card_expiry": "05/2023",
  "cvv": "987",
  "amount": 1000,
  "reference": "ORD98976",
  "customer_ip": "111.222.111.123",
  "currency": "AUD",
  "addendum_data": {
    "corp_l2": {
      "cardmember_reference": "ORD 123456 PO 08789",
      "description_1": "Box of paper",
      "quantity_1": 5,
      "total_1": 5000           
    }
  }
}

Addendum data is accepted for Purchase (Pre-auth and Purchase), and Captures, and should be included in the normal request payload, for example to include addendum data in a capture request:

{
  "amount": 10000,
  "addendum_data": {
    "corp_l2": {
      "cardmember_reference": "ORD 123456 PO 08789",
      "description_1": "Box of paper",
      "quantity_1": 5,
      "total_1": 5000           
    }
  }
}

If addendum data was presented with the original transaction (such as for a pre-auth) the data will be merged, with the most recent data overwriting the older data.
