HeyGen OAuth

📘

Note:

Before you can connect your app to HeyGen with OAuth 2.0, you'll need to be approved.

Please fill out this Integrations Intake form to apply to become a HeyGen Integration partner. Our Partnerships team will review your submission and get in contact.

This guide explains how to connect your application with HeyGen’s platform securely using OAuth 2.0. With OAuth 2.0, your application can access HeyGen resources on behalf of users without directly handling their sensitive credentials.

OAuth 2.0 provides a secure and standardized way for third-party apps to request authorization and access tokens. This process ensures that users can safely grant limited access to their HeyGen accounts while maintaining full control over their data.

For example, integrations like HeyGen’s Zapier Integration use OAuth 2.0 to connect user accounts and perform actions - such as generating videos - without exposing login information.

In this guide, you’ll learn about the complete authentication flow, including how to:

• Use the authorization and token endpoints
• Handle access tokens securely
• Maintain best practices for user authentication and data protection

Whether you’re building a new integration or adding HeyGen support to an existing app, this document outlines all the steps needed to implement a secure and efficient OAuth 2.0 workflow.
