# Overview

> User management and compliance verification

## Users API Overview

The **Users API** and **KYC Links API** allow you to register your end users, enabling seamless and compliant movement of stablecoins or fiat between your users' wallets or bank accounts. Carbn handles all **KYC (Know Your Customer)** and **KYB (Know Your Business)** verification steps, so you have confidence that your users meet all applicable compliance requirements.

***

### Key Concepts

* **Users**: Represent end users of your platform who need identity verification.
* **KYC/KYB**: Mandatory identity and business verification handled by Carbn Connect.
* **User Status**: Verification states (pending, approved, rejected) that determine transaction eligibility.
* **Risk Assessment**: Automated scoring system that evaluates compliance and regulatory requirements.
* **Document Verification**: Secure processing of government-issued IDs and business documents.
* **KYC Links**: Hosted verification flow alternative to direct API integration.

## User Registration

To register a new user, use either the **Users API** or the **KYC Links API**. Upon registration:

* Users must **agree to Carbn Connect's Terms of Service**.
* You must provide **basic identity information** such as:
  * Full name
  * Email address
  * Government-issued identifiers (e.g., SSN for individuals, EIN/TIN for businesses)

Carbn Connect will validate this information to approve the user for transactions. If additional information is needed, Carbn Connect will return precise requirements for completion of the KYC/KYB process.
