Which of these is required to ensure items are updated in the Guided Selling cart? Note: This question displayed answer options in random order when…

The putCartsItems method is the specific API action required to update items within the Industries CPQ cart. In the context of cart-based APIs, this method corresponds to an HTTP PUT request. It is designed to modify existing line items, such as changing their quantity or updating product attribute selections. While a handler like CpqAppHandler might invoke this logic, putCartsItems represents the direct, precise operation for performing the update, distinguishing it from actions like adding new items (postCartsItems) or retrieving cart data (getCartsItems).

A. done: A generic term for completing a process, not a specific API method for updating cart items.

B. vlcCart: Refers to a component or a variable, not an executable action or method for updates.

C. CpqAppHandler: A high-level controller or handler class that orchestrates cart operations, not the specific update method itself.

D. createCart: This method is used to instantiate a new cart, not to modify items in an existing one.

E. getCartsltems: A method to retrieve (GET) item data from the cart, not to update it.

F. getCartsProducts: A method to retrieve product information, not to update items within a specific cart.

H. postCartsltems: This method is used to add new items to the cart, whereas putCartsItems is used to update existing items.

I. checkout: The final step in the cart lifecycle to proceed with order creation, not for item modification.

J. submit: A generic action for form submission or finalization, not the specific cart update operation.

1. Salesforce Developer Documentation

Digital Commerce APIs: The "Update Items in a Cart" API is explicitly defined for this purpose. The documentation specifies the method as PUT and the endpoint as /v3/carts/{cartId}/items. This API is used to "update one or more items in a cart

for example

to change the quantity." This directly corresponds to the putCartsItems action.

2. Salesforce Help

Industries CPQ Cart-Based APIs: This documentation clearly distinguishes the roles of different HTTP methods for cart manipulation. It specifies that POST requests to the /items endpoint are for adding items

while PUT requests are for updating existing items. This confirms that putCartsItems is the correct choice for an update operation over postCartsItems.

3. Salesforce Industries CPQ Developer Guide: The guide details the architecture of the cart and its interaction with APIs. It describes the sequence of API calls for a typical Guided Selling session

where changes to quantities or configurations of items already in the cart trigger a PUT call to the cart items resource to ensure the cart state is updated correctly before validation or checkout.
