Available Extensions

This page lists all the extensions that are available for Salesforce Commerce. New extensions are added as they become available.

To create an extension provider, you must know which base Apex class to extend and the extension point name for mapping. Both the the base Apex class name and extension point name are listed for each extension.

This page lists two types of extensions: domain and endpoint.

Domain extensions extend functional domains, such as cart calculation. In contrast, endpoint extensions extend selected Connect API endpoints.

The release status and availability varies from extension to extension. This page is updated to reflect the latest release status of each extension.

The extensions listed in this section are all functionally related, and they all support cart calculations, including cart calculations that occur during checkout. These extensions comprise the Cart Calculate API.

Orchestrates multiple calculators to summarize the total cost in a cart. See Orchestrators and Calculators.

Each calculator is a separate extension that you can customize separately.

Base Apex class: CartExtension.CartCalculate
Extension point name: Commerce_Domain_Cart_Calculate
Namespace: CartExtension. See Cart Reference.

CartCalculate currently supports the following set of cart and checkout operations:

AddItemToCart
EditCartItem
DeleteCartItem
AddCoupon
DeleteCoupon
StartCheckout
PatchCheckout (address, set delivery method)

Calculates inventory for cart and checkout based on the inventory service.

Base Apex class: CartExtension.InventoryCartCalculator
Extension point name: Commerce_Domain_Inventory_CartCalculator
Namespace: CartExtension. See Cart Reference.

Reserves and tracks available inventory. By default, this extension uses the Omnichannel Inventory (OCI) system for inventory data.

Base Apex class: commerce_inventory.CommerceInventoryService
Extension point name: Commerce_Domain_Inventory_Service
Namespace: commerce_inventory. See Inventory Reference.

Calculates pricing for cart and checkout based on the pricing service.

Base Apex class: CartExtension.PricingCartCalculator
Extension point name: Commerce_Domain_Pricing_CartCalculator
Namespace: CartExtension. See Cart Reference.

Tracks how products and services are priced. By default, this extension uses Salesforce price books for pricing data. If your store uses Faster Add-to-Cart, make sure that all products have an entry in a store price book before implementing the pricing service extension.

Base Apex class: commercestorepricing.PricingService
Extension point name: Commerce_Domain_Pricing_Service
Namespace: commercestorepricing. See Pricing Reference.

Calculates promotions for cart and checkout. By default, this extension uses the Salesforce promotions service to perform its calculations.

Base Apex class: CartExtension.PromotionsCartCalculator
Extension point name: Commerce_Domain_Promotions_CartCalculator
Namespace: CartExtension. See Cart Reference.

Calculates shipping costs. By default, there is no charge for shipping, so you must extend the base Apex class to see any effect.

Base Apex class: CartExtension.ShippingCartCalculator
Extension point name: Commerce_Domain_Shipping_CartCalculator
Namespace: CartExtension. See Cart Reference.

Calculates taxes for cart and checkout. By default, this extension uses the Salesforce tax service to perform its calculations.

Namespace: CartExtension. See Cart Reference.

Applies taxes to products in the cart.

Base Apex class: commercestoretax.TaxService

The extensions listed in this section are used for checkout but don't affect cart calculations, so they aren't part of the Cart Calculate API.

During checkout, this extension creates an order using information from the cart.

Base Apex class: CartExtension.CheckoutCreateOrder
Extension point name: Commerce_Domain_Checkout_CreateOrder
Namespace: CartExtension. See Cart Reference.

During checkout, this extension arranges cart items across delivery groups. To implement custom Item Arrangement logic, extend the base Apex class and override the arrangeItems method.

Base Apex class: CartExtension.SplitShipmentService
Extension point name: Commerce_Domain_Shipping_SplitShipment

The extension listed in this section is used for Order Management.

Namespace: commerce_ordermanagement. See commerce_ordermanagement.

Unlike domain extensions, endpoint extensions extend the same base class.
