What should a developer use to retrieve products and display them to anonymous users for selection?

Using the Digital Commerce API to retrieve products for anonymous users is best achieved through the "Get Offers By Catalog" method. This approach is specifically designed to provide essential product offerings within a defined catalog, which is crucial for displaying relevant options to users without requiring them to sign in or create an account.

The advantage of this method lies in its capability to return a list of offers associated with a specific catalog, making it ideal for presenting various selection options to anonymous users. This enhances the user experience as they can browse available products that are grouped in a particular catalog context, facilitating informed choices.

In contrast, other methods might serve different purposes. For instance, searching for products might return a broader selection but could lack the contextual grouping found in catalog-specific offers. Listing all available products could overwhelm users with too much information, while retrieving specific product details is more effective for engaged users who have already shown interest. Thus, the selection of "Get Offers By Catalog" optimally aligns with the need to cater to anonymous users who are in the exploratory phase of their shopping journey.
