To check user permissions in Lightning web components, a developer should import two scoped modules: @salesforce/permission and @salesforce/customPermission. The @salesforce/permission module allows the developer to check if the user has access to a standard permission, such as View Setup or Modify All Data. The @salesforce/customPermission module allows the developer to check if the user has access to a custom permission, such as Enable Debug Mode or Manage Orders. The other modules do not exist or are not related to user permissions.

Two advantages of using Lightning Data Service are that it combines and de-duplicates server calls and that it loads record data progressively. Lightning Data Service is a service that provides access to Salesforce data and metadata in Lightning web components. It optimizes performance and minimizes server round trips by caching data on the client side and sharing data across components. It also combines and de-duplicates server calls by batching requests for the same record or object and returning a single response. It also loads record data progressively by returning available cached data first and then fetching updated data from the server asynchronously. Communicating with other components and converting between different data formats are not advantages of using Lightning Data Service, as they are not related to its functionality or features.

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.

Two aspects that are applicable to Page Includes are:

• Standard Visualforce controls such as apex:form should not be used within a page include. This is because the page include is rendered inside an existing Visualforce page that already has a form element. Using another form element inside the page include will cause conflicts and errors. Instead, the page include should use HTML elements or custom components that do not require a form element.
• Page Includes can be configured as Body Includes Begin. This means that the page include will be rendered at the beginning of the body section of the page, before any other content or widgets. This can be useful for adding some custom content or functionality that applies to the whole page, such as a banner, a modal, or a script. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Page Includes

Three steps that are necessary to have a subscriber page added to Salesforce B2B Commerce after creating a custom Visualforce page are:

• Create a new CC Subscriber Page record that points to your custom Visualforce page. This record will store information about the subscriber page, such as the name, description, URL, and Visualforce page. For example, you can create a new record named MySubscriberPage that points to your custom Visualforce page named MyPage.
• Refresh the Page Keys Index in CC Admin. This action will update the page keys index, which is a cache that stores the mapping between the page keys and the subscriber pages. You need to do this whenever you create or modify a subscriber page record.
• Enable the Subscriber Page in CC Admin. This action will allow you to select the subscriber page from the CC Page Settings configuration and assign it to a CC Page. For example, you can enable MySubscriberPage and assign it to the Home page. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Subscriber Pages

Two Salesforce B2B Commerce Visualforce pages that must be enabled at a Salesforce Community level to make the out of the box SEO functionality available are:

• CCSizeIndex: This page generates a sitemap.xml file, which is a file that lists all the pages and resources on a site that can be crawled by web crawlers. The page uses the configuration settings CO.SiteMapIncludeProducts and CO.SiteMapIncludeCategories to specify which products and categories should be included in the sitemap.
• CCCatSiteMap: This page generates a category sitemap file, which is a file that lists all the categories on a site that can be crawled by web crawlers. The page uses the configuration setting CO.SiteMapCategoryDepth to specify how many levels of subcategories should be included in the category sitemap.

For a solution that requires handling complex tax calculations across multiple countries and jurisdictions, it's efficient to leverage third-party tax services that specialize in this area. Implementing thesfdc_checkout.CartTaxCalculationsorsfdc_checkout.TaxCalculationsinterface to integrate with such a service ensures that tax calculations are accurate and up-to-date. Additionally, exploring the Salesforce AppExchange for packages or sample code can provide ready-made solutions or frameworks that can expedite the development process.

Two statements that are accurate about the Cart Item with a Type of Charge are that it is linked directly to a Cart Id and that it is linked directly to a Catalog Id. A Cart Item with a Type of Charge is a special type of Cart Item that represents an additional charge or fee that is applied to a Cart, such as shipping, handling, or tax. A Cart Item with a Type of Charge is linked directly to a Cart Id, which means that it belongs to a specific Cart and can be retrieved or updated along with other Cart Items. A Cart Item with a Type of Charge is also linked directly to a Catalog Id, which means that it references a specific Catalog that contains the products and prices for the store. A Cart Item with a Type of Charge is not created with the Cart Delivery Group Method after the shipping integration or after the freight integration, as these are not related to the creation of Cart Items. The Cart Delivery Group Method is a method that determines how products are grouped into delivery groups based on their shipping methods and addresses. The shipping integration and the freight integration are integrations that calculate and apply shipping costs and freight charges to a Cart or an Order.

Two methods from the platformResourceLoader module that are relevant for including third party JavaScript and CSS in a Lightning web component are loadScript and loadStyle. The platformResourceLoader module is a module that provides methods for loading JavaScript or CSS files from static resources or external URLs into a Lightning web component. The loadScript method is used to load a JavaScript file and execute it in the component. The loadStyle method is used to load a CSS file and apply it to the component. The loadClientScript method does not exist or is not relevant for including third party JavaScript in a Lightning web component. The loadCss method does not exist or is not relevant for including third party CSS in a Lightning web component. Salesforce References: Lightning Web Components Developer Guide: Load Scripts and Style Sheets, [Lightning Web Components Developer Guide: platformResourceLoader Module]

custom getter in a Lightning web component is a JavaScript function that executes logic each time a public property is accessed. A custom getter must start with the keyword get and be followed by a name for the property. A custom getter must also have a corresponding custom setter, which is a function that executes logic each time a public property is assigned a value. A custom setter must start with the keyword set and have the same name as the getter. One of the getter or setter functions must be annotated with @api, which makes the property public and reactive.

Option A and Option D show the correct syntax for defining a custom getter and setter for a public property called name. Option A shows the getter function, which returns the value of a private propertycalled _name. Option D shows the setter function, which assigns the value of the parameter value to the private property _name. The getter function is annotated with @api, which makes the name property public and reactive.

Option B and Option C are incorrect because they do not follow the syntax for a custom getter and setter. Option B shows a regular function declaration, not a getter function. Option C shows a regular assignment statement, not a setter function. Neither option uses the @api decorator, which is required for a public property. References:

Two kinds of queries that the methods in Salesforce B2B Commerce services perform by default are SOQL and schema-less queries. SOQL is the query language that is used to retrieve data from Salesforce objects and fields. Schema-less queries are queries that do not specify the object or field names explicitly, but use placeholders instead. For example, ccrz.ccServiceDao.getQuery('SELECT Id FROM Account WHERE Name = :name') is a schema-less query that uses :name as a placeholder for the field name. The framework will transform this query to use the actual field name based on the query transformation rules. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Query Transformation

You should avoid using ccLog in two scenarios. First, you should avoid using ccLog with System.LoggingLevel.ERROR when passing in a method invocation as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.ERROR, ‘D:something’, myCallToGetMessage(pl) ). This is because if an exception occurs within the method invocation, it will not be caught by ccLog and will cause an unhandled exception on the page. Instead, you should use a try-catch block around the method invocation and log the exception separately. Second, you should avoid using ccLog with System.LoggingLevel.DEBUG when passing in a large collection or object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrderList’, myOrderList), where myOrderList is a list of orders. This is because logging large objects can cause performance issues and consume a lot of heap space. Instead, you should use a loop to log only the relevant fields or properties of the object or collection. You can use ccLog with System.LoggingLevel.WARN when passing in a string as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.WARN, ‘D:something’, ‘Something unexpected occurred: The data we were expecting for pl was not there,’). This is a valid use case for logging a warning message. You can also use ccLog with System.LoggingLevel.DEBUG when passing in a small object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrder’, myOrder), where myOrder is an order object. This is acceptable as long as the object is not too large or complex. Salesforce References: [B2B Commerce Developer Guide: Logging]

When creating a tax provider, three things that a developer should consider first are: steps to complete in the tax service, how to handle results, and what to implement. Steps to complete in the tax service are the actions that the developer needs to perform to connect to and use the third-party tax service provider’s API or service. These steps may include authentication, authorization, request formatting, response parsing, error handling, and logging. How to handle results are the actions that the developer needs to perform to process and apply the tax calculation results from the tax service to the cart or order. These actions may include creating or updating cart items with type of Charge and charge type of Tax, applying taxadjustments or exemptions, and displaying tax amounts and details on the storefront. What to implement are the methods that the developer needs to define in their custom Apex class that implements the sfdc_checkout.TaxCalculations interface. The interface provides methods for customizing the tax calculation logic for a cart or an order, such as getTaxRatesAndRules, applyTaxAmountsAndAdjustments, and handleTaxErrorsAndExceptions. Whether to use JSON or XML is not something that the developer should consider first, as it is not a critical or relevant factor for creating a tax provider. It may depend on the format that the tax service provider supports or prefers, but it does not affect the overall functionality or performance of the tax integration. What events to fire in the Lightning web component is not something that the developer should consider first either, as it is not related to creating a tax provider. It may be an optional feature that the developer can add to enhance the user interface or user experience of their storefront, but it does not affect the core logic or functionality of the tax integration. Salesforce References: B2B Commerce Developer Guide: Tax Integration, [B2B Commerce Developer Guide: Tax Calculations Interface]

 Executing dynamic SOQL inside a without sharing class with a bind variable from PageReference.getParameters(), PageReference.getCookies(), or cc_RemoteActionContext class will open up a major security hole because these sources of input are not sanitized and can be manipulated by malicious users to inject SOQL queries that bypass the sharing rules and access data that they are not supposed to see. For example, a user can modify the URL parameters or cookies to include a SOQL query that returns sensitive data from the database. To prevent this, it is recommended to use static SOQL or escape the bind variables before executing dynamic SOQL.

 To make an integration available for selection, a developer must create a RegisteredExternalService record using Workbench and create an Apex class that uses the integration framework. Creating a RegisteredExternalService record using Workbench allows the developer to register their custom integration class as an external service in Salesforce B2B Commerce. The RegisteredExternalService record contains information such as the class name, version, display name, description, and category of the integration class. The category determines where and how the integration class can be used in B2B Commerce, such as ShippingService or TaxService. Creating an Apex class that uses the integration framework allows the developer to define custom logic for integrating with an external service provider’s API or service. The integration framework provides interfaces and classes for various types of integrations, such as shipping, tax, payment, inventory, and freight. The developer can implement these interfaces and classes in their custom Apex class and override their methods with their own logic. Modifying the StoreIntegratedService to map to an Apex class ID using Workbench is not a required step for making an integration available for selection, as it is only used for registering internal services that are provided by Salesforce B2B Commerce out-of-the-box. Entering the integration class name and version in store administration is not a required step either, as it is only used for selecting an existing integration class that has already been registered as an external service. Salesforce References: [B2B Commerce Developer Guide: Integration Framework], [B2B Commerce Developer Guide: RegisteredExternalService Object]

To investigate a suspected bug in a checkout flow, comparing previous versions of the flow with the current one can help identify changes that might have introduced the bug. Additionally, Salesforce provides debugging capabilities within the Flow Builder, where a developer can select the debug option, provide input values known to trigger the issue, and execute the flow to observe its behavior, aiding in pinpointing the source of the problem.

Two guidelines for logging that are used within the core Salesforce B2B Commerce product are:

• The close method of ccrz.ccLog must be called at the end of the remote action. This method will flush the log messages to the browser console or to a custom object, depending on the logging mode. If this method is not called, the log messages may not be displayed or saved properly.
• No calls to ccrz.ccLog can be made before cc_CallContext.initRemoteContext is executed. This method will initialize the call context object, which contains information such as the current user, cart, storefront, and configuration settings. These information are required for logging, so calling ccrz.ccLog before initializing the call context will result in an error. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Logging

In Lightning Web Components, the decorators@api,@track, and@wireplay crucial roles. The@apidecorator is used to expose public properties and methods, making them accessible to other components. The@trackdecorator is used to mark private properties as reactive, so the UI updates when their values change. The@wiredecorator is used to wire Apex methods or Salesforce data to the component. Salesforce documentation on LWC development extensively covers these decorators, explaining their usage and best practices.

To enable a new payment type for the Checkout flow, three possible configuration metadata descriptors are needed:

• *.pay: This descriptor defines the payment type name, label, description, icon, and handler class. For example, CO.pmts.CreditCard.pay defines the payment type for credit card payments.
• *.Edit: This descriptor defines the Visualforce page that is used to edit or update an existing payment of this type. For example, CO.pmts.CreditCard.Edit defines the page that allows editing a credit card payment.
• *.New: This descriptor defines the Visualforce page that is used to create a new payment of this type. For example, CO.pmts.CreditCard.New defines the page that allows creating a new credit card payment. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Payment Configuration Settings

 To make a Lightning web component available in the Lightning Page Builder or Experience Builder, the developer needs to do two things: set the isExposed property to true in the component’s metadata file, and define at least one target that specifies where the component can be used, such as a Lightning page type or a flow screen. Redeploying the component or closing and reopening the browser will not make the component appear in the searches if the metadata file is not configured properly. References:

To enable Salesforce B2B Commerce logging in the managed package, you need to do two steps. First, you need to save a value in the Logging Token input field in the Global Settings section of CC Admin. This value can be any string that you choose, such as “debug”. Second, you need to ensure that the value saved in the Logging token field is appended to the ccLog query parameter in the URL of the storefront page that you want to debug. For example, if your logging token is “debug”, then your URL should look like this: https://my-storefront.com/?ccLog=debug. This will enable logging for that page only. You do not need to turn on the checkbox “Cloudcraze Logging” in CC Admin, as this is an old setting that is no longer used. You also do not need to set a cookie with the Id of the user accessing the storefront in CC Admin, as this is not required for logging. Salesforce References: [B2B Commerce Developer Guide: Logging]

 According to the Lightning Web Components Developer Guide, Shadow DOM is a standard that encapsulates the internal document object model (DOM) structure of a web component. Encapsulating the DOM gives developers the ability to share a component and protect the component from being manipulated by arbitrary HTML, CSS, and JavaScript. Shadow DOM also provides style and behavior isolation for a web component, which means that the styles and scripts defined inside a component do not affect the rest of the page, and vice versa. Therefore, the purposes of the Shadow DOM in a Lightning web component are to encapsulate the internal DOM structure of a web component (A) and to allow components to be shared while protecting them from being manipulated by arbitrary code (B). The other options are incorrect because Shadow DOM does not allow direct access to the document object model of the component ©, nor does it allow older JavaScript libraries to manipulate the tagging structure (D). References: Lightning Web Components Developer Guide, Understand the Shadow DOM Unit
