# KYC Attestation (KYC Reliance)

## Overview

KYC Attestation (also known as KYC Reliance) allows merchants with their own KYC provider to share verified user data with Coinflow without requiring users to re-verify. This method requires pre-approval from Coinflow's compliance team.

> **Note**: This method is for non-Sumsub KYC providers. If you use Sumsub, see [Sumsub Token Sharing](/api-reference/api-reference/withdraw/create-kyc-share-token).

## Who Should Use This Method

KYC Attestation is ideal for merchants who:

* Have an existing KYC provider (other than Sumsub)
* Want to avoid duplicate KYC verification for users
* Can demonstrate compliance with regulatory standards
* Have their KYC process approved by Coinflow's compliance team

## Setup Process

### Step 1: Request the Questionnaire

Contact Coinflow to receive the KYC Reliance Questionnaire. This document assesses whether your KYC process meets Coinflow's compliance standards.

### Step 2: Submit for Review

Complete and submit the questionnaire to Coinflow's compliance team. Final approval is required before you can use KYC attestation in production. Compliance review typically takes 2-4 weeks.

### Step 3: Enable in Sandbox

Once your application is under review, request Coinflow to enable KYC attestation for testing:

* Provide your sandbox merchant ID
* Test the integration in your sandbox environment

### Step 4: Integrate the API

After receiving compliance approval, integrate the [KYC Attested Endpoint](/api-reference/api-reference/withdraw/create-kyc-attested) into your production environment.

## If Not Approved

If your KYC reliance application is not approved, you can fall back to [passing external KYC data](../what-is-kyc#passing-external-kyc-data-to-coinflow), which allows you to submit user documents for Coinflow to verify.
