Authentication
HeyGen offers multiple integration paths — MCP, Skills, and Direct API — each with its own authentication method. Understanding which flow applies to your use case will determine how you authenticate and how usage is billed.
OAuth 2.0
Used for MCP integrations. Users authorise access through a standard consent screen — no API keys needed. Requires an active HeyGen web plan with premium credits. Usage is deducted from your web plan's premium credit balance.
API key
Used for Skills and Direct API integrations. Authenticate by passing your API key via the X-Api-Key header. Requires a HeyGen API key generated from Settings → API in your dashboard. Usage is deducted from your API dashboard balance, which is separate from web plan credits.

API Pricing – Frequently Asked Questions
What are the different ways to integrate with HeyGen?
HeyGen offers three integration paths: MCP for connecting to AI assistants like Claude without having to manage APIs, Skills for extending AI coding agents like Claude Code and Cursor, and Direct API for complete programmatic control over video generation.
How does authentication function for each integration path?
MCP uses OAuth — users authorise via a consent screen with no API keys needed. Skills and Direct API both use an API key passed via the X-Api-Key header, generated from Settings → API in your HeyGen dashboard.
Are MCP credits and API balance the same thing?
No. MCP usage is deducted from the premium credit balance of your web plan, while Skills and Direct API usage is deducted from your API dashboard balance. The two billing pools are independent.
What is the minimum amount needed to get started with Pay-As-You-Go?
You can get started with as little as $5. Simply top up your API wallet and pay only for what you use — no monthly commitment is required.
What additional benefits does the Enterprise plan provide compared to Pay-As-You-Go?
Enterprise includes everything in Pay-As-You-Go, along with customised scalability, dedicated developer support, Digital Twin Creation API, Proofread API, and discounted rates.
