# Introduction

If you're tracking online sales, you can submit a batch of conversion data from your site via a .CSV file uploaded via an FTP/SFTP/FTPS connection. This integration method is useful in circumstances where you can't integrate JavaScript (e.g., impact.com's Universal Tracking Tag) or server-side API calls onto your site.

{% endhint %}

## How it works

1. impact.com tracking links will dynamically populate your site's landing page URLs with an `im_ref` value. You'll need to capture and store this value in a first-party cookie or server-side. It should be present across all domains and pages of your site.
2. Online sales that occur on your site (conversions) are recorded via the system you use to track your conversions. This data needs to be populated in a .CSV file, along with the recorded `im_ref` value (among other required parameters) present when a visitor converted.
3. You’ll submit a .CSV file with your conversion data and other required parameters that’s uploaded to impact.com. This file can be submitted via an FTP/SFTP/FTPS connection automatically on a set cadence (usually daily), emailed to a unique email address provided by impact.com, or pulled from your own FTP server.

**Warning:** Integrating with impact.com requires web development expertise — it's strongly recommended to enlist the help of a skilled web developer to complete the integration.
