# 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 with the subject line "API Integration Request". ## 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
