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

PatchCheckout (address, set delivery method)

Base Apex class: CartExtension.InventoryCartCalculator

Base Apex class: CartExtension.PromotionsCartCalculator
Extension point name: Commerce_Domain_Promotions_CartCalculator

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.

The extension listed in this section is used for checkout but doesn't affect cart calculations, so it isn'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
