Used for MCP integrations. Users authorize 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.
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.
Use HeyGen with your favorite platforms
Connect HeyGen to your favorite tools to automate video creation.
HeyGen offers three integration paths: MCP for connecting to AI assistants like Claude without managing APIs, Skills for extending AI coding agents like Claude Code and Cursor, and Direct API for full programmatic control over video generation.
MCP uses OAuth — users authorize 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.
No. MCP usage is deducted from your web plan's premium credit balance, while Skills and Direct API usage is deducted from your API dashboard balance. The two billing pools are independent.
