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
