REST API design principles map resource modeling to predictable URL structures and apply standard HTTP methods like GET, POST, PUT, and DELETE for intuitive endpoint behavior. This ensures consistent resource naming, clear action mapping, and predictable interactions across typical API scenarios.

Error handling and versioning in a RESTful API require structured error responses and scalable versioning strategies to manage changes. Applying these guidelines ensures robust error reporting and backward-compatible API evolution without disrupting existing consumers.

Designing pagination and filtering for nested REST resources involves applying consistent query parameters to manage large datasets and retrieve specific subsets. This approach maintains predictable endpoint behavior across complex resource hierarchies like users, products, and orders.

These REST API guidelines apply directly to an e-commerce application by structuring users, products, and orders as predictable endpoints. You can implement resource modeling, pagination, filtering, and nested resources to build an intuitive and consistent API.

Using PUT versus PATCH in REST API design depends on whether you are replacing a full resource or applying partial modifications. Following standard HTTP method usage guidelines ensures predictable and intuitive state transitions for API consumers.
