PaymentCompleted

PaymentCompleted is a term used in payment processing systems to denote that a payment transaction has been fully processed and settled. It indicates that the payer’s funds have been authorized, captured, and cleared, and that the merchant has received the payment amount or is prepared to receive settlement from the payment processor. In many implementations, PaymentCompleted is the final state in the transaction lifecycle; preceding states commonly include PaymentAuthorized, PaymentPending, and PaymentCaptured.

In practice, a PaymentCompleted event or status will include identifying data such as a transactionId, orderId, amount, currency, timestamp, and paymentMethod. It may also reference settlement details or platform-specific metadata. The exact semantics can vary by system: some gateways mark completion when capture succeeds and funds are scheduled for settlement, while others require an explicit settlement step.

Reliability considerations include idempotency to prevent duplicate completion signals, reconciliation with bank statements, and robust logging. Security considerations emphasize PCI DSS compliance, tokenization of payment data, and fraud monitoring.

Operationally, PaymentCompleted often triggers downstream processes such as inventory release, order processing, customer notifications, and financial reporting. If a completion signal is later contradicted by a reversal or chargeback, appropriate refund or reversal workflows must be invoked.
