# Sending Product Data Using Flat Files

## Overview

The purpose of these documents is to describe how to format, structure and send data to the Fredhopper Access Server (FAS) and Fredhopper Suggest. The document focuses on standard functionality and best practices which should be implemented in all integrations. It does not cover any customer-specific requirements.
