Universal Containers is preparing their storefront to use Open Commerce APIs (OCAPI).

The hook dw.ocapi.shop.basket.calculate is ideal for integrating taxation logic when preparing a storefront to use OCAPI in Salesforce B2C Commerce Cloud. This hook allows the system to apply custom business logic, such as tax calculations, each time the basket's totals are calculated. This ensures that the order totals remain consistent and accurate across various customer interactions and API calls.

Option B (dw.ocapi.shop.basket.calculate): Correctly applies tax logic during the calculation of basket totals, which is critical for ensuring that all updates to the basket (like adding items, applying discounts, or changing quantities) consider tax implications correctly.

This approach aligns with the best practices for extending OCAPI in Commerce Cloud to maintain consistency in order totals, especially when the basket state changes.
