B2B Commerce for Developers Accredited Professional AP-202 B2B-Commerce-Developer Exam Questions with Experts Answers Updated Recently

 To implement the use of a third-party service for either tax, shipping, or pricing calculation in a B2B Commerce store, a developer must complete these three tasks:

• Create an Apex class that implements the appropriate interface for the calculation type. For example, for tax calculation, the developer must implement the sfdc_checkout.CartTax interface and define the getTax method. This method takes a Cart object as an input parameter and returns a list of CartTax objects with the calculated tax amounts.
• Create a named credential for authentication with the external service. A named credential specifies the URL of a callout endpoint and its required authentication parameters. The developer can use the named credential in the Apex class to make the callout to the external service and handle the response.
• Register the Apex class as the integration in the store administration. The developer must specify the Apex class name in the corresponding field for the calculation type. For example, for tax calculation, the developer must enter the Apex class name in the Tax Calculation Integration field. This way, the store can invoke the Apex class to perform the calculation for each cart.

The other options are not valid tasks for implementing the use of a third-party service. Creating a flow to call the external service directly is not supported for B2B Commerce, and creating an Apex class with an invocable method is not required for the calculation integration. References:

Two viable ways that a developer can import some new product data contained in a JSON file one time are running a command like: sfdx force:data:tree:import -f NewProducts.json -u and converting the JSON to a CSV file and using Data Loader to import it. Running a command like: sfdx force:data:tree:import -f NewProducts.json -u allows the developer to import data from a JSON file into an org using Salesforce CLI commands. The sfdx force:data:tree:import command is a Salesforce CLI command that imports data into an org using JSON files that conform to the SObject Tree API specification. The SObject Tree API specification is a format that defines how records are represented in JSON files for data import or export. The -f flag specifies the path of the JSON file that contains the data to be imported. The -u flag specifies the username or alias of the org where the data will be imported. Running this command will create records in the org based on the data in the JSON file. Converting theJSON to a CSV file and using Data Loader to import it allows the developer to import data from a CSV file into an org using Data Loader. Data Loader is a tool that allows users to import or export data between Salesforce and CSV files. The developer can use an online converter or a spreadsheet application to convert their JSON file into a CSV file that matches the structure and format of their Salesforce object. The developer can then use Data Loader to import the CSV file into their org and create records based on the data in the CSV file. Converting the JSON to an xlsx file and using Workbench to import it is not a viable way to import some new product data contained in a JSON file one time, as Workbench does not support xlsx files for data import or export. Workbench is a web-based tool that provides access to various Salesforce features and functionalities, such as data manipulation, REST Explorer, and Apex Execute. Running a command like: sfdx force:data;import:bulk -f NewProducts.json -u is not a viable way either, as there is no such command as sfdx force:data;import:bulk. The correct command for importing data using bulk API is sfdx force:data:bulk:upsert.

To verify changes by using an external service, a developer can use either of these two ways:

• Create an Apex class that implements the sfdc_checkout.CartShippingCharges interface and defines the getShippingCharges method. This method takes a Cart object as an input parameter and returns a list of CartDeliveryGroupMethod objects with the updated shipping charges. The developer then needs to register the Apex class as the Shipping Calculation Integration in the store administration. This way, the store can call the external service to calculate the shipping charges for each delivery group in the cart.
• Create an Apex class that defines a method to retrieve the shipping charges from an external service and update the Cart Delivery Group Method object. The developer then needs to invoke this method from a trigger on the Cart Delivery Group Method object. This way, the store can update the shipping charges whenever the delivery group method is inserted or updated.

The other options are not valid ways to verify changes by using an external service. Creating a flow using an action is not supported for B2B Commerce, and creating a trigger on the Cart Delivery Group object will not update the shipping charges for each delivery group method. References:
