server.append()extends an existing SFRA route by adding middlewareafter the existing middleware chain. It does not replace or bypass the middleware already defined onHome-Show. Therefore, the consent-tracking middleware, cache middleware, and original route logic execute first; after they callnext(), the appended custom function executes.

Salesforce explicitly describesserver.appendas a customization mechanism that causes the original middleware chain to execute together with the additional appended step. It is commonly used when a cartridge must enrich an existing route without duplicating or replacing the base implementation.

The custom controller does not need to repeatconsentTracking.consentorcache.applyDefaultCachesimply because those functions are already part of the inherited route. Option B would become relevant if a middleware filtering condition itself rejected the request, but the absence of those declarations in the appended step does not inherently produce a parameter-mismatch error.

The resulting execution order is therefore: original middleware and base route logic, followed by the appended custom logic.

SFRA is designed around cartridge-based extension rather than direct modification of the base storefront code. When a developer needs to add another step to an existing registration workflow, the route should beextendedfrom a custom cartridge so that the standard implementation remains intact.

Salesforce's SFRA customization guidance describesmodule.superModule,server.extend,server.append,server.prepend, and route replacement as the supported mechanisms for customizing functionality from another cartridge. The exact technique depends on whether the additional operation must execute before, after, or instead of existing behavior.

Option A implies modifying the original controller directly, which is undesirable because upgrades or cartridge replacement can overwrite the changes. Option B copies base code, creating duplication and making later maintenance significantly harder.

Extending the route preserves the original implementation and keeps merchant-specific logic isolated in the custom cartridge. For a simple additional step that should execute after the existing route,server.append()is often appropriate; for access behavior or a fundamentally changed workflow, Salesforce recommends the corresponding supported extension/replacement pattern.

The correct B2C Commerce Service Framework type isHTTP Form. An HTTP Form service is implemented bydw.svc.HTTPFormServiceand is designed to send parameters as URL-encoded name/value pairs in an HTTP POST body.

Salesforce's Script API states that HTTP Form Service requests useapplication/x-www-form-urlencodedand that arguments supplied tocall()are URL encoded into the request body. Salesforce's Service Framework documentation likewise listsHTTP Formas an available Business Manager service type and explains that itscreateRequestprocessing constructs a URL-encoded form POST by default.

There are no B2C Commerce service types called 'POST Form' or 'HTML Form.' POST is an HTTP request method rather than the Business Manager service-type identifier, and HTML describes document markup rather than the integration transport.

The service type should therefore be registered as HTTP Form, with the URL, authentication, timeout, credentials, and profile configured through the normal Service Framework objects.

OCAPI permissions are configured againstresource IDs, not against one particular inventory-list identifier embedded in an individual request. In the example URL, the principal API resource family isinventory_lists;ecom-inventoryis merely the identifier of the particular inventory list being accessed.

Therefore, the developer should inspect the OCAPI Data API settings for a resource rule covering theinventory_listsresource path, such as an appropriate/inventory_lists/...pattern, and verify that the required HTTP method and attribute selectors have been permitted.

Theclient_ididentifies the external application whose permissions are being evaluated, but it does not identify the inventory API resource being enabled. Similarly,ecom-inventoryis instance/business data and should not be confused with the API resource family.

This distinction is central to OCAPI authorization. A client configuration associates a client ID with resource path patterns, allowed HTTP methods, andread_attributes/write_attributesselectors. Requests are authorized only when they match an enabled resource and method.

When an SFRA controller inherits an existing route and usesserver.append()to add another middleware function, the appended function is addedafter the existing middleware chain. The developer does not need to repeat all of the middleware that already belongs to the base route.

Salesforce states directly thatserver.appendcauses a route to execute both theoriginal middleware chain and any additional appended steps. Therefore, provided the custom controller correctly extends the base server module and callsnext(), the original route executes first and the appended custom code executes afterward.

Omitting the existing middleware declarations from the appended function does not itself generate a parameter-mismatch runtime error. The inherited route retains its consent, cache, authentication, metadata, or other middleware steps. Option C reverses the execution sequence expected from an append operation.
