ICheckoutManagerBase (Checkout)

CheckoutManagers are used to manage the most aspects of the checkout workflow. Merchello's default CheckoutManager is the BasketCheckoutManager which is intended to be used for basket checkout outs.

🚧

CheckoutManager supersede the SalePreparation in earlier versions.

Prior to Merchello 1.14.0, the SalePreparation class was used to manage the checkout workflow.

The CheckoutManager breaks down the checkout workflow into several logical areas which can be seen in the ICheckoutManagerBase interface. Each area is managed by a specific lazy loaded area checkout manager.

ICheckoutManagerBase

/// <summary>
    /// Defines the base checkout workflow.
    /// </summary>
    public interface ICheckoutManagerBase : ICheckoutContextManagerBase
    {
        /// <summary>
        /// Gets the checkout manager for customer information.
        /// </summary>
        ICheckoutCustomerManager Customer { get; }

        /// <summary>
        /// Gets the checkout extended manager for custom invoicing.
        /// </summary>
        ICheckoutExtendedManager Extended { get; }

        /// <summary>
        /// Gets the checkout manager for marketing offers.
        /// </summary>
        ICheckoutOfferManager Offer { get; }

        /// <summary>
        /// Gets the checkout manager for shipping.
        /// </summary>
        ICheckoutShippingManager Shipping { get; }

        /// <summary>
        /// Gets the payment.
        /// </summary>
        ICheckoutPaymentManager Payment { get; }
    }

Contextual information is shared between the managers via a CheckoutContext .

Replacing the default CheckoutManager(s)

Developers can write their own area managers to augment the default behavior and provide additional application specific functionality by implementing the following

Checkout area	Base class
Customer	CheckoutCustomerManagerBase
Extended	CheckoutExtendedManagerBase
Offer	CheckoutOfferManagerBase
Payment	CheckoutPaymentManagerBase
Shipping	CheckoutShippingManagerBase

After you've created your class, you can then modify the type reference in the Merchello.config
