What is a post-authorization?

post - au - tho - ri -za - tion
noun

Post-authorization, often referred to as "post-auth," is the immediate phase following the approval of a transaction. During this crucial step, the system undertakes several tasks, including the collection of payment, verifying the successful completion of the transaction and updating relevant records. Think of it as the necessary follow-up process that ensures all elements are properly settled once you've granted authorization for the payment to proceed. This step plays an important role in confirming the transaction's accuracy and completeness.
