HeyGen Automation

Automate AI-powered video creation workflows -- browse avatars and templates, generate personalized videos from templates, track processing status, and retrieve shareable URLs -- all orchestrated through the Composio MCP integration.

Toolkit docs: composio.dev/toolkits/heygen

Setup

Connect your HeyGen account through the Composio MCP server at https://rube.app/mcp

The agent will prompt you with an authentication link if no active connection exists

Once connected, all HEYGEN_* tools become available for execution

Core Workflows

1. Browse Available Templates

Retrieve pre-designed avatar templates from the HeyGen library for video creation.

Tool: HEYGEN_V2_TEMPLATES

No parameters required -- returns template IDs, names, preview images, and customization options.

Use this to discover templates before generating videos. Each template has a unique ID needed for generation.

2. Inspect Template Details & Variables

Retrieve the full structure of a template including all variables, scene mappings, and customization options.

Tool: HEYGEN_RETRIEVE_TEMPLATE_DETAILS_V3

Parameter	Type	Required	Description
`template_id`	string	Yes	Template ID from `HEYGEN_V2_TEMPLATES` or the HeyGen dashboard

This is a required prerequisite before generating videos -- it tells you exactly which variables must be populated.

3. Browse Available Avatars

List all realistic avatars available for video creation, useful for mapping characters to scenes.

Tool: HEYGEN_V2_AVATARS

No parameters required -- returns avatar identifiers, names, and preview images.
The list may be paginated; additional calls might be needed for the full set.

4. Generate Video from Template

Create a customized video by populating a template with your variables and content.

Tool: HEYGEN_V2_TEMPLATE_GENERATE

Provide a video title and all template variables discovered via HEYGEN_RETRIEVE_TEMPLATE_DETAILS_V3. Every required variable must be supplied with exact names and types.

5. Check Video Processing Status

Poll the processing status and retrieve metadata for a video being generated.

Tool: HEYGEN_RETRIEVE_VIDEO_STATUS_DETAILS

Parameter	Type	Required	Description
`video_id`	string	Yes	Video ID returned from the generation API

Returned URLs expire after 7 days but can be regenerated by calling this endpoint again.

6. Get Shareable Video URL

Generate a public, shareable link that allows anyone to view the video without authentication.

Tool: HEYGEN_RETRIEVE_SHARABLE_VIDEO_URL

Provide the video_id to receive a public URL for distribution.

Known Pitfalls

Pitfall	Details
All template variables required	`HEYGEN_V2_TEMPLATE_GENERATE` demands every variable from `HEYGEN_RETRIEVE_TEMPLATE_DETAILS_V3` with exact names and types -- missing or misnamed fields break scenes or fail generation
Always inspect templates first	Never skip `HEYGEN_RETRIEVE_TEMPLATE_DETAILS_V3` before generation -- multi-scene templates have complex variable structures
Video URLs expire	URLs from `HEYGEN_RETRIEVE_VIDEO_STATUS_DETAILS` expire after 7 days; regenerate by calling the endpoint again
Paginated avatar lists	`HEYGEN_V2_AVATARS` may return paginated results -- additional calls may be needed for the full library
Processing time varies	Video generation is asynchronous; poll `HEYGEN_RETRIEVE_VIDEO_STATUS_DETAILS` until status is complete before using output URLs
