Payment Processing and Settlement¶

Here’s a simplified example of a successful payment and subsequent settlement, involving a credit card.

Payment Processing

1. The client selects a product or service on the trading platform, goes to the payment form, fills out the necessary fields, and clicks «Pay».
2. QIWI receives a request to process the operation.
3. QIWI sends a request to the payment system that services the card.
4. The payment system sends a request to the bank that issued the client card.
5. The issuing bank updates the client account amount and sends a successful transaction response to the payment system.
6. The payment system sends a successful transaction response to QIWI.
7. QIWI informs the partner about the successful completion of the operation.

Settlements

As a result of payment processing, funds accumulate and, when a certain amount is reached or after a specific number of days, they are transferred to the partner’s settlement account in their chosen credit institution.
