Overview
What is credit card payment processing?
Credit card payment processing is the sequence that securely sends a customer's card transaction for authorization, returns an approval or decline result, records the order, and moves funds under the provider's settlement terms. AtomicPay combines this payment step with a one-page checkout, Brazil-ready fields, attribution, subscriptions, sales recovery, and connected purchase events.
