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
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
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.
