The B2B Commerce for Developers Accredited Professional exam validates your ability to customize and extend Salesforce B2B Commerce storefronts through code. It covers custom Lightning Web Components for storefront pages, Apex extensions for pricing and inventory logic, checkout flow customization, and API integrations with external fulfillment and ERP systems.

The largest portion of the exam — 25% — focuses on Custom Storefront Components, covering LWC development, Commerce components, and page customization. Roughly 25% of the questions address checkout customization, covering custom pricing, shipping, tax, and payment integrations. B2B Commerce Development Model carries the heaviest weight at 20%, covering data model, APIs, and extension points. Together, these domains form the backbone of the certification and warrant the bulk of your preparation time.

Beyond the core areas, the exam also evaluates complementary skills. Questions on integration development make up 20% of the test, which spans external system connectivity, Apex callouts, and platform events. The largest portion of the exam — 10% — focuses on testing and deployment, which spans unit testing, debugging, and environment management. Although individually lighter, these topics frequently appear in scenario-based questions that blend multiple skill areas.

 Custom checkout flow extensions are tested frequently — understand how to implement custom Apex classes for pricing, shipping, and tax that hook into the standard checkout pipeline. Practice building a custom LWC component that displays on a B2B storefront page and interacts with Commerce APIs.

Question #1 - Handle and manage LWC development, Commerce components, and page customization to deliver reliable platform solutions that meet real-world business demands

A developer needs to customize the B2B Commerce product detail page to display technical specifications from a custom object related to the Product.

What development approach should the developer use?

A) Create a custom Lightning Web Component (LWC) that queries the related technical specifications and embed it on the product detail page using Experience Builder
B) Modify the standard B2B Commerce source code directly
C) Build a Visualforce page to replace the entire product detail page
D) Use inline CSS to add specification text to the existing component

 

Correct answers: A – Explanation:
Custom LWCs extend B2B Commerce pages without modifying core code. The component queries related data and renders within the Experience Builder page layout. This maintains upgradeability. Source: Salesforce Docs: B2B Commerce Dev

A developer needs to implement custom pricing logic that applies volume discounts based on total cart quantity across all items, not just per-product quantity.

What extension point should the developer use?

A) Modify price book entries after each cart update
B) Implement a custom pricing integration using the B2B Commerce pricing extension point (RegisterPricingProvider) that evaluates total cart quantity and applies volume-based discounts during cart calculation
C) Add discount codes that buyers must enter manually
D) Build a batch job that recalculates cart prices every 5 minutes

 

Correct answers: B – Explanation:
B2B Commerce pricing extensions allow custom logic during cart calculation. RegisterPricingProvider executes custom Apex that evaluates cart-wide conditions (total quantity) and applies dynamic pricing. Source: Trailhead: Lightning Web Components Basics

A developer needs to customize the checkout flow to add a shipping method selection step that queries real-time shipping rates from a third-party carrier API.

How should the developer implement this?

A) Create a custom checkout component and implement the shipping integration using B2B Commerce’s shipping extension point (RegisterShippingProvider) that calls the carrier API and returns available methods with calculated rates
B) Hard-code shipping rates in the checkout configuration
C) Offer only one shipping method with a flat rate
D) Let buyers choose shipping after the order is placed

 

Correct answers: A – Explanation:
B2B Commerce shipping extensions (RegisterShippingProvider) execute during checkout to calculate real-time shipping options. Custom Apex calls the carrier API and returns methods with prices for buyer selection. Source: Trailhead: B2B Commerce

A developer needs to implement a custom tax calculation that integrates with Avalara for real-time tax computation during B2B Commerce checkout.

What extension point should the developer use?

A) Use a lookup table of tax rates stored in a custom object
B) Implement the B2B Commerce tax extension (RegisterTaxProvider) with custom Apex that calls the Avalara API during checkout, passing cart items and shipping address for accurate tax calculation
C) Calculate tax manually after order placement
D) Apply a flat tax rate to all orders regardless of jurisdiction

 

Correct answers: B – Explanation:
RegisterTaxProvider executes during checkout to calculate taxes. Custom Apex calls Avalara with cart items and address, returning jurisdiction-specific tax amounts. This ensures compliance across different tax regions. Source: Salesforce Docs: Apex Guide

A developer needs to build a custom search results page that displays product cards with enhanced styling, quick-add-to-cart functionality, and comparison checkboxes.

What development approach should be used?

A) Override the default search component with a Visualforce page
B) Build a custom LWC that uses B2B Commerce’s wire adapters and APIs to retrieve search results, render custom product cards with styled layouts, and implement add-to-cart and comparison actions using the Commerce SDK
C) Embed an iframe from a third-party search tool
D) Use CSS-only modifications to the standard search results

 

Correct answers: B – Explanation:
Custom LWCs leverage B2B Commerce wire adapters for data retrieval and the Commerce SDK for cart operations. This provides full control over the search results presentation and functionality. Source: Trailhead: Flow Builder

A developer needs to create a custom cart component that displays a savings summary showing how much the buyer saves compared to list price.

What data should the component access?

A) Only the final price from the cart
B) A hardcoded savings percentage
C) An external pricing database
D) Access the cart item data including list price, negotiated price, and quantity through the B2B Commerce cart APIs, then calculate and display the per-item and total savings using a custom LWC with computed fields

 

Correct answers: D – Explanation:
Cart APIs provide list price, negotiated price, and quantity per item. The LWC computes savings (list – negotiated) per item and for the total cart, displaying a savings summary that reinforces value. Source: Salesforce Docs: REST API

A developer is implementing an integration that syncs B2B Commerce orders to the company’s ERP system for fulfillment upon order confirmation.

What integration approach should the developer use?

A) Manual order export and email to the fulfillment team
B) A shared database between Salesforce and the ERP
C) A nightly batch export of all orders
D) Implement a Platform Event or trigger-based integration that fires when an Order record is created in Salesforce, transforming the order data to the ERP’s format and sending it via API callout

 

Correct answers: D – Explanation:
Event-driven integration (Platform Events or triggers) fires immediately on order creation, sending order data to the ERP for timely fulfillment. Data transformation maps Salesforce order fields to ERP format. Source: Trailhead: Apex Testing

A developer needs to implement a custom inventory check that verifies product availability from an external warehouse management system before allowing checkout completion.

What B2B Commerce extension should be used?

A) Display a static ‘In Stock’ label for all products
B) Implement the inventory extension point (RegisterInventoryProvider) that calls the WMS API during checkout to verify availability for each cart item, blocking checkout if items are out of stock with informative error messages
C) Check inventory only after the order is placed
D) Allow checkout without inventory validation

 

Correct answers: B – Explanation:
RegisterInventoryProvider executes during add-to-cart and checkout to validate availability in real time. The custom Apex calls the WMS API and returns stock status, preventing overselling. Source: Salesforce Docs: LWC Guide

A developer needs to write Apex tests for a custom B2B Commerce pricing extension that applies tiered discounts.

What testing approach should the developer use?

A) Test only in a sandbox with manual cart interactions
B) Deploy to production untested and monitor for issues
C) Create Apex test classes that mock the pricing context (cart items, quantities, price books), invoke the pricing extension with test data covering each discount tier, and assert that calculated prices match expected values for all scenarios
D) Skip testing since the pricing logic is simple

 

Correct answers: C – Explanation:
Apex tests for commerce extensions mock the context (cart items, quantities) and verify pricing calculations across all tier scenarios. Automated tests run in CI/CD and catch regressions. Source: Trailhead: Apex Integration

A developer wants to add a ‘Request a Quote’ button on the B2B Commerce product detail page for products that require custom pricing for large orders.

What should the developer implement?

A) Remove the product from the store and handle quotes offline
B) A custom LWC with a Request Quote button that opens a modal form collecting quantity, requirements, and timeline, then creates a Quote request record in Salesforce linked to the buyer’s Account and the product, notifying the sales team
C) A static phone number to call for quotes
D) A mailto: link to the sales team

 

Correct answers: B – Explanation:
A custom LWC provides an in-context quote request experience. The modal captures requirements, creates a structured Quote request in Salesforce, and notifies sales — maintaining the digital experience. Source: Trailhead: Data Security
