# Confirm Payment

> Confirm a pre-authorized payment and capture the reserved funds.

This endpoint captures the reserved funds of a pre-authorized payment. You can confirm the full reserved amount or a partial amount less than or equal to the original pre-authorization.

<Info>
  If you specify an `amount` lower than the original pre-authorized amount, only that partial amount is captured and the remaining funds are released back to the customer.
