Episode 6: API Design

The brief compares REST, gRPC, SOAP, and WebSocket for an API design decision.

For a wishlist feature, REST is the best fit for add, remove, and list actions across browser and mobile clients.

WebSocket is only justified when the app needs real-time updates, such as price-drop notifications.

The key takeaway: match the interface style to the use case to avoid needless complexity and maintain compatibility.
