Answer
Action results allow APIs to return proper HTTP responses.
- Return 200, 404, 400 etc.
- Provide flexibility using IActionResult
- Support multiple return formats
Quick Answer
Action Results are objects returned from controller actions that determine the HTTP response. Common: Ok(data) -> 200, Created(uri, data) -> 201, BadRequest(errors) -> 400, Unauthorized() -> 401, NotFound() -> 404, NoContent() -> 204. Use ActionResult as return type for both typed returns and IActionResult alternatives. They abstract HTTP status codes from business logic.
