Use this to discover templates before generating videos. Each template has a unique ID needed for generation.
2. Inspect Template Details & Variables

Type
Required
Description
template_id

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

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.

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
