Pre-Authorization

Use this information to process a pre-authorization for an initial amount. This transaction places a temporary hold on the customer's payment card. The transaction amount can be captured at a later time.

Most authorizations expire in 5 to 7 days. The issuing bank sets this period of time. When an authorization expires with the issuing bank, your bank or processor might require you to re-submit an authorization request and include a request for capture in the same message. For more information, see Capture.

Follow these steps to process a pre-authorization.

Create a

ChargeParameters

object and provide the required information for the payment.

Use the

startChargeTransaction

method to initiate the transaction flow.

let chargeParameters = ChargeParameters(amount: Decimal(1.00),
                                        currency: .USD,
                                        customIdentifier: "yourReferenceForTheTransaction",
                                        autocapture: false)

let charge = await mposUi.startChargeTransaction(with: chargeParameters)

After the transaction is completed, get the results of the transaction.

switch charge {
    case .success(let transaction):
        print("Transaction with id: %@ completed with state: %@", transaction.identifier, transaction.status)
    case .failure(let error):
        print("Transaction failed with error: %@", error.localizedDescription)
    }

To get complete transaction details, access the

object.
