# API

## Overview

Vcheck’s API Platform integrates our services and workflows in a fast and secure manner, with two options available:

1. **General Integration**: A flexible API that accepts various data formats, allowing you to send candidate investigation, ID verification, and monitoring requests directly from your system.
2. **Integration with Greenhouse Webhook**: A specialized API for automating candidate ID verification directly from your Greenhouse account.

> To request API credentials, contact us at <support@vcheckglobal.com> with the subject line "API Integration Request".&#x20;

## Authentication & Security

Vcheck Platform’s REST APIs use API Keys for authentication. The API Key is a unique security code that must be included in the headers of each request. It ensures secure access and controls different permissions.
