Error toasts are automatically displayed for all API errors (except 401, 404, and cancelled requests) with user-friendly messages based on status codes. Success toasts can be enabled for mutation operations (POST, PUT, DELETE, PATCH) using the withSuccessToast helper. Created apiToastHelper.ts utility with helper functions for manual toast control. Toasts can be disabled per-request using withoutErrorToast helper."
