Incremental Authorization
Definition
Increases an existing authorization hold without a new authorization, for cases where the final amount grows after the initial auth (hotels, rideshare, tabs, fuel).
Incremental authorization raises the amount of an existing authorization hold without creating a separate authorization. It is used when the final charge grows after the initial auth — hotel stays, car rentals, rideshare, bar tabs, and fuel are the common cases. By extending the existing hold, a merchant keeps the eventual capture within an authorized amount instead of running a second, disconnected authorization. Support varies by scheme, card type, merchant category, and acquirer or PSP, and is not universally available.
Incremental authorization solves a specific problem: you took an authorization for one amount, but the final bill grew. Rather than running a second, disconnected authorization — which can leave two holds on the cardholder’s account and complicate the eventual capture — incremental authorization raises the existing hold so the final capture stays within an authorized amount.
Where it shows up
The pattern is most common where the total is unknown at the start and climbs as the engagement runs: hotel stays where the guest adds room service or extends a night, car rentals with fuel and mileage charges, rideshare and taxi fares, open bar tabs, and fuel pumps that authorize an estimate before the actual fill is known. It often follows an initial pre-authorization taken at the start of the stay or ride.
Support varies by scheme, card type, merchant category code, and acquirer or PSP, and it is not universally available — confirm with your provider before relying on it. For how incremental authorization fits into the broader authorize-capture-settle flow, see the payment lifecycle guide.
