77. Frage
Given this customer basket information:
* A customer has an existing basket that consists of multiple items.
* One of the items is identified as a gift item by an attribute at the product line item.
* The developer needs to write custom code to fetch the customer basket and then modify the basket based upon the items in the cart. If the basket contains any gift items, modify the basket and create a separate shipment for the gift item.
Four hooks are required to make the modification, beginning with modifyGETResponse and ending with validateBasket.
* dw.ocapi.shop.basket.modifyGETResponse
* -- missing hook --
* -- missing hook --
* dw.ocapi.shop.basket.validateBasket
What are the two missing hooks in the middle?
Antwort: C
Begründung:
The required workflow creates a new shipment for a gift item and then modifies shipment information associated with the basket. The OCAPI basket shipment hooks corresponding to those two operations aredw.
ocapi.shop.basket.shipment.beforePOSTanddw.ocapi.shop.basket.shipment.beforePATCH.
Salesforce ' s OCAPI hook documentation definesshipment.beforePOSTas the extension point executed before creation of a shipment andshipment.beforePATCHas the extension point executed before modification of an existing shipment. Those operations align directly with the described solution: establish the separate shipment and then apply the necessary changes before final basket validation.
The alternatives involvingbeforeDELETEorafterDELETEare inconsistent with the scenario because no shipment needs to be deleted. The requirement is to separate a gift product into its own shipment, not remove a shipment from the basket.
The concludingvalidateBaskethook provides the final validation stage after the basket/shipment changes have been processed, allowing custom logic to ensure that the resulting basket remains valid.

A Digital Developer needs to store information temporarily and decides to create a custom object.
Which code creates a custom object?
Antwort: B
79. Frage
A Newsletter controller contains the following route:
Server.post('Subscribe', function (req,res,next){
var newsletterForm = server.forms.getForm('newsletter');var CustomObjectMgr = require('dw/object/CustomObjectMgr'); if(newsletterForm.valid){ try{ var CustomObject = CustomObjectMgr.createCustomObejct('NewsletterSubscription', newsletterform.email.value); CustomObject.custom.firstName = newsletterForm.fname.value; CustomObject.custom.lastName = newsletterForm.lname.value;-
} catch(e){
//Catch error here
}
}
next();
});
Assuming the Custom Object metadata exists, why does this route fail to render the newsletter template when the subscription form is correctly submitted?
Antwort: A
80. Frage
Which of these situations is an appropriate use of the B2C Commerce OCAPIs?
Antwort: C
Begründung:
OCAPI is designed to expose B2C Commerce resources to external applications and integration systems through RESTful APIs. A warehouse management system that needs to update inventory is therefore a strong OCAPI use case because inventory is enterprise data maintained by an external operational system and must be synchronized into Commerce.
Salesforce describes the OCAPI Data API as providing external applications with programmatic access to Commerce resources and administrative data operations. Inventory integration is a standard example of synchronizing Commerce with external inventory or fulfillment systems.
Extending a System Object Type definition with new attributes is a platform metadata/configuration activity normally performed through Business Manager or supported metadata import mechanisms, not an ordinary OCAPI runtime integration. Showing customer information on the storefront ' s native My Account page is also normally handled internally by SFRA controllers, models, templates, and the B2C Commerce Script API rather than calling OCAPI from the same storefront application.
Using OCAPI for the warehouse system preserves a clear integration boundary: the external application authenticates through the API and exchanges inventory data without being coupled to storefront presentation code.
Study Guide reference:Application Development - OCAPI, external-system integrations, inventory synchronization, Data API usage, and storefront versus integration architecture.
