The lessons teach how payments flow. This lesson is the lookup table behind them: every authorization type, every operation, every status a payment, refund, dispute, subscription, or payout can be in, every stored-credential code, and every dispute reason code, brand by brand.

It was compiled from Visa, Mastercard, American Express, Discover, Apple, Google, and Stripe documentation, plus acquirer documentation where the networks do not publish rules openly. Items marked processor come from acquirer or processor documentation rather than the network's own rulebook. Treat those as reliable but confirm them with your provider.

Reference tables
TypeWhat it isWhen to useBrand notes
Final authorizationThe amount is final and will be captured in full.Most online retail where the price is known.Mastercard: must match the clearing amount and currency, and be cleared or reversed within 7 days; capturing more needs a new auth, capturing less triggers a fee.
Pre-authorization / estimated authorizationAn estimate that may change before capture. The cardholder must be told it is an estimate.Hotels, car rental, restaurants with tips, fuel, made-to-order goods.Visa: estimated indicator; 0.02% fee on estimated and incremental auths. Mastercard: pre-auth valid 30 days and priced slightly higher than final processor. Amex: estimated auth with set variances by industry (for example 15% for card-not-present retail).
Undefined authorizationAn authorization sent without a pre-auth or final indicator.None. It is the legacy default.Mastercard: valid 7 days; penalized with a per-transaction fee in the US from July 2025. Always send an indicator. processor
Initial authorizationA capped amount authorized before the final is known, at unattended terminals.Automated fuel pumps.Visa: no incrementals allowed; complete or reverse within 2 hours.
Incremental authorizationRaises an existing estimated authorization.Hotel stay extended, rental runs long.Visa: adds to the hold but does not extend validity; linked by the original transaction ID. Mastercard: each increment restarts the 30-day pre-auth window. Amex: needs an estimated auth sent with the indicator, an approval, and a charge not yet submitted.
ReauthorizationA new authorization after the first expired.Back-orders and split shipments that ship late.A Visa industry-practice MIT. Mastercard uses partial shipment (M205) instead. Amex: if shipping more than 7 days after order, authorize at order and again at shipment.
Partial authorization (partial approval)The issuer approves less than requested; the customer pays the rest another way.Prepaid and debit cards with a low balance.Visa: merchant signals support; approval comes back as response code 10; all prepaid issuers must support it; mandated for debit and prepaid in many card-present categories since April 2024. Amex: debit and prepaid only, not cross-border, not recurring.
Account verification ($0 auth)Checks the card is valid without holding money. Can run address and security-code checks.Saving a card with no charge due.Visa: a $1 test auth instead of $0 counts as misuse. Mastercard: called Account Status Inquiry (ASI); a nominal-amount auth approved then reversed draws a fee.
Extended authorizationA longer validity window than standard.Long fulfillment, travel.Visa Extended Authorization Service: up to 30 days for card-not-present CITs, for a 0.08% fee processor. Mastercard pre-auth already allows 30 days. Amex travel: duration of stay or rental.
OvercaptureCapturing slightly more than authorized, within network tolerance, without a new auth.Tips, small final adjustments.Tolerances vary by brand and category, for example about 15% for Visa by default and 20% to 30% for restaurants. processor
MulticaptureSeveral partial captures against one authorization, then a final capture.Split shipments inside the validity window.Provider support required. Without it, a single partial capture usually releases the rest of the hold. processor
Authorization reversal (full or partial)Releases all or part of a hold.Cancelled order, final amount lower than authorized.Visa: within 24 hours of knowing the sale will not complete, or of completing for less. Mastercard: commonly 24 hours processor; the hard limits are reversal or clearing within 30 days for pre-auths and 7 days for final auths, or a processing integrity fee applies. Amex (international rules): mandatory within 24 hours if you will not submit the charge.

Card network rules change. Time limits, fees, and authorization windows here reflect published rules and provider documentation as of late 2026; confirm details with your processor before you build against them.
