Among the supplied choices, B is the only approach consistent with robust B2C Commerce integration design: the application must inspect service results, preserve useful diagnostic information, and implement controlled error behavior rather than blindly proceeding.
However, " log all responses " must be interpreted according to Salesforce ' s secure logging practices. Raw responses mustnotbe persisted indiscriminately when they contain passwords, access tokens, personal information, payment data, or other sensitive content. B2C Commerce ' s Service Framework provides logging controls such as response/request filtering specifically so that sensitive information can be removed before it reaches diagnostic logs.
Ignoring a failed API response, as in A, can produce corrupt application state or misleading storefront behavior. Option C is equally problematic because silently converting failures into successful responses prevents calling code and shoppers from receiving appropriate failure handling.
A correct production implementation examines the Service Framework result, logs sanitized diagnostic context where appropriate, implements fallback behavior when the business process allows it, and returns a controlled application response.
