Pre-Authorization Completion

NEW!   We now have our Interactive tool for this section.

Retrieves funds that have been locked and prepares them for settlement into the merchant’s account.

Things to consider:

  • Pre-Authorization Completion is also known as "capture" or "completion".
  • A Pre-Authorization transaction can only be completed once.
  • To reverse the full amount of a Pre-Authorization transaction, use the Pre-Authorization Completion transaction with the amount set to 0.00.
