<ConnectorHeader data={connector} name="Kount KHash" />

Kount KHash is a utility connector that generates a KHASH value for a tokenized card. It provides a secure way to produce a Kount-specific, one-way, irreversible hash of a card number for use with Kount's Risk Inquiry Service (RIS).

This connector does not process payments or make fraud decisions. It is a tool to enable integration with Kount's fraud analysis platform.

## How it works

To perform advanced fraud analysis, Kount's services require a proprietary hash of the card number (KHASH). This allows Kount to identify a card across its global network without exposing the sensitive card number.

The Kount KHash connector:

* **Reduces PCI scope** - Generate a KHASH without the raw card number reaching your servers
* **Simplifies Kount integration** - Get the required KHASH to use in server-side calls to Kount's fraud analysis APIs
* **Enables flexible workflows** - Use Kount's fraud tools independently of the payment processor

## Credentials

When setting up Kount KHash in the dashboard, configure the following credentials:

* **Hash Salt Key** - The Kount hash salt key used to generate the KHASH.

## Usage

1. Add the Kount KHash connector in the Gr4vy dashboard and enter the hash salt key.
2. Send the raw card details (card number, expiration date) to the Kount KHash connector through the API.
3. Receive the generated KHASH in the response.
4. Use the KHASH in server-side API calls to Kount's Risk Inquiry Service (RIS) to get a fraud score before proceeding with a payment.
