Amount Adjustment API

Overview

The Adjust Amount API allows you to modify the authorized amount of a pre-auth transaction before capture. This is typically used in scenarios where the final charge differs from the initially authorized amount due to changes such as discounts, additional fees, or partial order fulfillment.

This API is used after a successful pre-authorization, when the merchant needs to increase or decrease the authorized amount prior to capturing the funds.
