To structure a Laravel API with repository pattern and service layers, route requests through FormRequest validation into thin controllers, which delegate to services handling transactions and side effects, then use repository interfaces for data access and API Resources for responses.

DTOs between layers in a Laravel backend project ensure predictable data transfer by separating typed objects from Eloquent models. This keeps service orchestration clean, prevents accidental mass assignment, and enforces a strict boundary between business and data layers.

The best way to refactor fat controllers in a multi-developer Laravel project is to extract validation into FormRequests, move business logic into transactional service classes, bind repository interfaces in the container, and shape responses using API Resources.

Yes, this Laravel service layer approach supports queued side effects and transactions. Services orchestrate transactional business logic and dispatch queued jobs after successful operations, while centralized exception handling ensures failures roll back without corrupting data.

FormRequests and API Resources work together in a layered Laravel architecture by separating input validation from output formatting. FormRequests authorize and validate incoming data before it reaches the controller, while API Resources transform Eloquent models into consistent JSON responses.

Repository interfaces in a Laravel API add abstraction that benefits team-scale development and complex transactional logic, but they introduce unnecessary overhead for simple CRUD operations or solo projects where direct Eloquent access within controllers is sufficient.
