What Is Authorization Code? Definition, Payment Flow, and Examples
Authorization Code is an identifier returned with an approved transaction for later capture and reconciliation; it is not a security password. This guide focuses on Authorization Code's real role, boundaries, and common points of confusion.
Key points
- Definition: Authorization Code is an identifier returned with an approved transaction for later capture and reconciliation; it is not a security password.
- Flow position: The merchant sends an authorization request, and the issuer side returns an approval or decline based on account, amount, credentials, risk, and product rules.
- Do not confuse: Authorization Code / Decline Code
How it fits into the payment flow
For Authorization Code, the relevant process is as follows: The merchant sends an authorization request, and the issuer side returns an approval or decline based on account, amount, credentials, risk, and product rules. Authorization codes, response data, and decline codes describe that decision; they are not capture, posting, or final merchant funding.
A practical review of Authorization Code should account for this: A merchant should handle declines according to response information and network rules without exposing sensitive internal detail. A soft decline may support an appropriate authentication or retry path, while repeated submission is not a sound answer to a hard decline.
Practical example
An approved transaction returns an authorization code that the merchant retains for capture and reconciliation linkage. It helps match records and is not a password for the cardholder to enter.
