Core Workflows
1. Browse Available Templates
Retrieve pre-designed avatar templates from the HeyGen library for video creation.
Tool: HEYGEN_V2_TEMPLATES

---
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.

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.

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 |
