Salesforce B2B-Commerce-Developer Exam With Confidence Using Practice Dumps

The REST APIs in Salesforce B2B Commerce support pass-through parameter handling by passing parameters through the service handlers. This means that any parameters that are not recognized by the REST API framework will be passed to the service handler class that implements the API logic. The service handler class can then use these parameters for custom logic or validation.

The developer should use the getPicklistValues wire adapter to retrieve metadata about a specific picklist. This wire adapter allows the developer to get the picklist values for a specified field on a given object and record type. The wire adapter returns an object that contains the picklist values, the default value, and the controlling field (if any). The developer can use this wire adapter to populate a custom picklist component with the appropriate values based on the object and record type context. The other options are incorrect because they are not valid wire adapters for retrieving picklist metadata. References: getPicklistValues, Retrieving Picklist Values Without Using Apex, B2B Commerce and D2C Commerce Developer Guide

According to the B2B Commerce Developer Guide, the ICart interface provides access to the cart object and its related data. The Details property of the ICart interface returns an ICartDetails object, which contains information about the cart such as the currency, the subtotal, the shipping cost, the tax, and the grand total. The Fields property of the ICartDetails interface returns a map of field names and values for the cart object. Therefore, to get the grand total amount for items in the cart and in the currency of the cart, a developer should use the expression {ICart.Details.Fields.grandTotal}, which returns the value of the grandTotal field from the cart object. References: B2B Commerce Developer Guide, ICart Interface, ICartDetails Interface
