Two things that happen with the cart during tax implementation are that new entries are written to the cart and previous entries are deleted from the cart. A tax implementation is an integration that calculates and applies tax rates and amounts to a cart or an order based on various factors, such as product type, price, quantity, location, and tax rules. A tax implementation can use either an external tax service provider or custom Apex code to perform the tax calculation. When a tax implementation is invoked for a cart, it writes new entries to the cart with a type of Charge and a charge type of Tax. These entries represent the tax amounts and adjustments that are applied to the cart. Before writing new entries to the cart, the tax implementation deletes any existing entries with a type of Charge and a charge type of Tax from the cart. This ensures that the tax calculation is accurate and up-to-date based on the current state of the cart and avoids any conflicts or inconsistencies with previous tax entries. Previous entries are not copied to another object or modified with the new tax calculation, as these are not valid actions for handling existing tax entries.

A best practice when passing query parameters from user interface to an apex controller is to query parameters should be properly sanitized by using JSINHTMLENCODE within the VisualForce Page or Component. This function will encode any special characters in the query parameters to prevent cross-site scripting (XSS) attacks or SOQL injection attacks. For example, ccrz.ccRemoteActions.getProducts('{!JSINHTMLENCODE(searchTerm)}') will encode the searchTerm parameter before passing it to the apex controller.

Three actions that a developer must take, in a B2B Commerce store, to accept credit card payments using a client’s chosen payment provider are: create a named credential for authentication with the payment provider, create an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface, and create a PaymentProviderGateway record for the custom payment provider class. Creating a named credential for authentication with the payment provider allows the developer to securely store and manage authentication information, such as username, password, token, or certificate, for connecting to the payment provider’s API or service. Creating an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface allows the developer to define custom logic for processing credit card payments using the payment provider’s API or service. The interface provides methods for validating credit card information, authorizing payments, capturing payments, voiding payments, and refunding payments. Creating a PaymentProviderGateway record for the custom payment provider class allows the developer to register the custom payment provider class as a payment gateway in the store and associate it with a payment method. Creating a RegisteredExternalService record for the custom payment provider class is not a required action, as this is only used for registering external services that are not related to payment processing, such as tax or shipping services. Creating an Apex class that implements the commercepayments.PaymentGatewayAdapter interface is not a required action either, as this is only used for D2C Commerce stores, not B2B Commerce stores.
