Post Authorization (Post-Auth)

Post Authorization, often referred to as Post-Auth, is a specific type of credit card transaction process that occurs when a voice authorization has been obtained for a transaction. This typically happens in scenarios where an immediate electronic authorization is not possible due to various reasons such as technical issues with the payment terminal or limits on the card that require manual override.

Key Aspects of Post Authorization:

Post Authorization is a critical process for transactions that cannot be immediately authorized through standard electronic means. It ensures that merchants can complete sales while maintaining transaction security and compliance, even under exceptional circumstances. This method is particularly valuable in high-value transactions or in situations where connectivity issues prevent standard electronic authorization.
