Incremental Authorization (Type 75) is used to secure additional authorization for an ongoing, previously authorized transaction. This transaction type is limited to certain card types.

Transaction types Auth Only (01) and Incremental Auth (75) are very similar and are treated as such by the Elavon Gateway applications. If an Incremental Auth (75) is submitted and the application determines that the card type, industry, and processor requires an Auth Only (01) be used, it is automatically changed. Otherwise, the application will process the transactions as an incremental authorization.

This transaction type requires some settings or operation specific to Restaurant industry transactions for tipping:
- Authorization tolerance value is set to 100%.
- Fusebox disables checking for both incremental authorizations and authorization reversals.
- Incremental Auth transactions are not generated automatically.

## Auto Authorize Difference flag
The Auto Auth Difference flag within the Fusebox Boarding Configuration, Card Types screen also influences how an Incremental Authorization operates:

- If the Auto Authorize Difference flag is set to Yes, when a Prior-Auth Sale (07) is run and the final amount is greater than the authorized total tolerance percentage (except 100%), the application automatically creates an Incremental Authorization.
- If the Auto Authorize Difference flag is not enabled, the user receives an error message: -16 Final Amt Too Large, if the amount is greater than the total authorized amount by more than the Auth Tolerance percentage (except 100%).
- If an Incremental Auth(75) is run without an Auth Only (01) to reference, it changes the Incremental Auth to an Auth Only.

Incremental Authorizations (75) and Authorization Reversals (Type 76) are both reflected in the transactions total amount authorized (Field 0130). CPS field data is automatically maintained by the Elavon Gateway software and should never be passed by your POS application. 

:::::notice{note}
Incremental authorization does not require cardholder account number because the Elavon token or unique ID tracks the transaction from the original authorization.
