# Unit

> Use Knot's direct integration with Unit to securely retrieve and send card information without backend requests.

## Overview

Knot has a [direct integration with Unit](https://www.unit.co/docs/partnerships/partner-tokens/#unit-customers-requesting-a-partner-token-set-up) and is set up as a `partner user` on Unit's platform in order to retrieve card information. This integration can be used to securely send card information to Knot without your backend needing to make any requests.

## Setup

<Steps>
  <Step title="Contact Unit" titleSize="h3">
    Contact your Customer Success Manager at Unit to request that Knot be allowed to retrieve end-user information from Unit in both **sandbox** and **production**. Once this is complete, notify Knot.
  </Step>

  <Step title="Notify Knot" titleSize="h3">
    Once Unit has confirmed that Knot may retrieve card information on your users, notify the Knot team.
  </Step>

  <Step title="Knot configures your integration" titleSize="h3">
    Knot will configure your integration to enable Unit as the method of retrieving card information. As a result, you will not be required to provide end-user card information to Knot in the `/card` endpoint.
