Automatic Partial Authorization Reversal {#payments-auth-reversal-automatic-partial-overview}
=============================================================================================

Automatic partial authorization reversals are supported for:

* Credit cards
* Debit cards and prepaid cards.
* Quasi-cash.

If the capture amount is less than the authorization amount, `Cybersource` automatically performs a partial authorization reversal before it sends the capture request to the processor. The results of a successful partial authorization reversal are:

* The capture amount matches the new authorization amount at the payment card company.
* The hold on the unused credit card funds might be released. The issuing bank decides whether or not to release the hold on unused funds.  
  Not all issuers act on a request for a partial authorization reversal. Therefore, `Cybersource` cannot guarantee that the funds will be released.
