Fiserv Authorization Type Added to Transactions

Backoffice Transactions

What's New?

Backoffice GET transaction endpoints now return an AuthorizationType key-value pair within the transactionDiscretionaryFields array. This makes it easier to identify, reconcile, and categorize authorization activity in your transaction data.

Possible values for AuthorizationType: Purchase · Pre Auth Request · Pre Auth Complete · Reversal · Return · Generate Token

The authorization type value is sourced from Fiserv's Client Line Enterprise (CLX) reporting file.

If CLX does not provide an authorization type or provides an empty string, there will be no AuthorizationType key-value pair in the transactionDiscretionaryFields.

Example Response (abbreviated)

{
    "id": 12551,
    "transactionDate": "2025-03-11T17:29:08+00:00",
    ...
    "transactionDiscretionaryFields": [
        {
            "key": "AuthorizationType",
            "value": "Return"
        }
    ],
    ...
}

Filtering

AuthorizationType is not available as a filter parameter. To locate authorization-only transactions, filter by fundingStatus of Auth Only via the API or Backoffice Transactions page (Status > Auth Only), then review the AuthorizationType value on each returned record.

Backoffice UI

Authorization Type is now also available in the Backoffice UI and Submerchant Portal. See more information in our PayOps and Launchpay release notes.
