# Create Podcast

`POST /v3/podcasts`

## Request

- Base URL: `https://api.heygen.com`
- URL: `https://api.heygen.com/v3/podcasts`
- Auth: one of:
  - API key in header `x-api-key`
  - HTTP bearer

Generate a multi-avatar conversational podcast video from a topic and/or source files plus two avatars. Generation is asynchronous — use the returned podcast_id to poll status via GET /v3/podcasts/{podcast_id}.

## Headers

- `Idempotency-Key` string

## Request body

- CreatePodcastRequest: Request body for POST /v3/podcasts.
  - `topic` string, nullable: Free-text topic / angle / instructions for the conversation. Provide `topic`, `source_files`, or both.
  - `source_files` union[]: Grounding documents (PDF/image/video) the script is built from. Provide each as {type: 'url', url: '...'} or {type: 'asset_id', asset_id: '...'}. Provide `topic`, `source_files`, or both.
    - union
      - AssetUrl: Asset input via publicly accessible HTTPS URL.
        - `type` 'url', required: Input type discriminator
        - `url` string, required: Publicly accessible HTTPS URL for the asset
      - AssetId: Asset input via HeyGen asset ID from the asset upload endpoint.
        - `type` 'asset_id', required: Input type discriminator
        - `asset_id` string, required: HeyGen asset ID from the asset upload endpoint
  - `host_avatar_id` string, required: Avatar id for the host.
  - `guest_avatar_id` string, required: Avatar id for the guest.
  - `host_voice_id` string, required: Voice id for the host. List voices via GET /v3/voices.
  - `guest_voice_id` string, required: Voice id for the guest. List voices via GET /v3/voices.
  - `layout` 'landscape' | 'portrait': Output aspect ratio: 'landscape' (16:9) or 'portrait' (9:16).
  - `duration` 'auto' | '1min' | '2min' | '3min' | '5min': Target spoken length. 'auto' lets the generator pick the length.
  - `instructions` string, nullable: Free-form scene/studio instructions (e.g. setting, tone). Used verbatim to describe the studio when set.
  - `callback_url` string, nullable: Optional webhook URL. When set, HeyGen POSTs a notification here when the podcast reaches a terminal state (completed or failed), so you don't have to poll GET /v3/podcasts/{podcast_id}.
  - `callback_id` string, nullable: Caller-defined identifier echoed back in the webhook payload so you can correlate the callback with this request.
