Reserve Capture Flow

  • The reserve capture flow utilizes a two-step process: reserving funds (authorization) and then capturing them to complete the payment.

  • Funds can be captured using asynchronousCaptureFundsReservation or released using asynchronousCancelFundsReservation if the transaction is canceled.

  • After capture, an Acquirer Reference Number (ARN) is generated and should be provided to Google via setAcquirerReferenceNumberForCaptureNotification for dispute and fraud management.

  • Captured payments can be refunded using asynchronousRefund or may undergo chargebacks handled through the dispute flow.

  • Reservations automatically expire after a set period, typically seven days, if not captured or canceled.

Reserve Capture Flow

Overview

The reserve capture flow is used to handle payments using dual message communication. The funds are first reserved through a call to the Payment Integrator hosted reserveFunds method. If this method synchronously returns SUCCESS it means that the funds are reserved and can be captured or released. This step is commonly known as an performing an Auth or Authorization.

Capture funds reservation

The funds can be captured by a call to asynchronousCaptureFundsReservation. This will start the process of moving the funds into Google's account. Reserve Capture

Cancel funds reservation

Alternatively, the reservation of funds can be canceled with a call to asynchronousCancelFundsReservation. This frees the hold on the funds. If a reservation is canceled there is no money movement. Reservations are automatically canceled after a fixed period of time, typically seven days. Cancel Funds

Acquirer reference number

If the funds are captured, a ARN (Acquirer Reference Number) is generated. That value is usually not known to the Payment Integrator until a few days later. Once the value is known, the Payment Integrator must call the Google hosted setAcquirerReferenceNumberForCaptureNotification to provide the ARN to Google. Associating the ARN with this transaction allows Google to handle disputes and fraud related to this transaction.

Subsequent operations

If the funds are captured, the payment may be refunded by Google with a call to the Payment Integrator hosted asynchronousRefund method. Alternatively, the user or issuing bank can start the chargeback process which is handled through the dispute flow.
