Quick Answer
Organize large Web API endpoints: feature-based folder structure (Features/Orders/OrdersController.cs). Keep controllers thin - delegate to services/handlers. Use MediatR: each action dispatches a command/query, handler contains logic. Version namespaces (Controllers/V1/, Controllers/V2/). Separate API routes by domain area. Keep controller files small - split by resource if they grow large.
Use feature-based folder structure instead of traditional controller-based.
Group routes using /api/v1/[module]/[controller].
Use Areas for large domains.
Apply consistent naming and versioning strategies.
