What to build

If the payment is an authorization you haven't captured yet, capture only the amount you're keeping: the unused part of the hold is released. If it's already captured, send a Reversal with an amount. The rest stays authorized, and you can send further partial reversals until the reversed total reaches the authorized amount.

What this means for PCI

This is guidance rather than a compliance determination. Which questionnaire you are eligible for depends on your full environment, so confirm it with your QSA or your acquirer before you rely on it.

Worth knowing

Confirm the operation is in the transaction's allowedActions list before you send it. The processor, its reversal window, and the merchant's own settings all change that list, and none of them is visible from your side.
Not every processor supports a partial reversal. One that doesn't refuses the request with REVERSAL_PARTIAL_NOT_SUPPORTED, and your options are a full cancel or waiting for settlement and refunding the difference.
An authorization can be captured once. Capturing less releases the remainder for good, so capture when the order's final amount is known.
