# Add slides to a live creation

`PATCH /v1/presentations/{presentationId}`

## Request

- Base URL: `https://bisque.today`
- URL: `https://bisque.today/v1/presentations/{presentationId}`
- Auth: HTTP bearer

Send the whole HTML again with new sections appended. Existing slides keep their keys and order (`LIVE_APPEND_ONLY` otherwise); unchanged slides carry their audio forward, assets the body leaves out are kept, and the response names the slides that need narrating with an upload target for each, exactly as create does. Add `baseRevision`, the `live.revision` the slides were written against, and an append that fell behind is refused (`LIVE_REVISION_CONFLICT`) rather than overwriting slides it never saw; an append waits up to 20 seconds for another append or narration upload in progress, and is refused with `LIVE_APPEND_IN_PROGRESS` if it is still going. `live.revision` on the presentation rises by one and anyone watching sees the new slides without a reload. API-key callers only.

## Path parameters

- `presentationId` string, required

## Request body

- PublishNarratedRequest
  - `indexHtml` string, required: The whole `html-presentation/v1` file.
  - `title` string: Overrides the title parsed from the HTML.
  - `slug` string: URL slug under your channel. Reuse it to republish.
  - `presentationId` string: Republish an existing presentation by id instead of slug.
  - `handle` string: Which of your channels to publish on; defaults to your account's.
  - `dryRun` boolean: Sandbox: run every check a real create runs (format, slug and org conflicts, tier cap, credit preflight) and write nothing. The reply is a 200 with status `validated`.
  - `visibility` 'public' | 'unlisted' | 'private' | 'org': Who can open the watch link. Unlisted unless you say otherwise; `org` publishes into the bisque.team organization named by `org`.
  - `org` string: bisque.team organization slug; publishes into the company space.
  - `contextMd` string: Agent-facing background shipped with the bundle as `context.md`.
  - `designMd` string: Design notes shipped with the bundle.
  - `voiceId` string: Narration voice tag; defaults to the account's saved voice.
  - `madeWith` string[]: Models credited with making this presentation — e.g. ["Claude Opus 5", "Kokoro af_heart"]. Free text, shown to viewers in the watch page's ⋯ menu. Omit to keep what a previous publish recorded; send `[]` to clear it.
  - `description` string: Plain-text description shown under the player on the watch page, with web URLs linked — a summary, then the sources. Omit to keep what a previous publish sent; send an empty string to clear it.
  - `speechSpeed` number: Narration speed. 1.0 is normal.
  - `voiceStability` number: How closely the voice keeps to its reference, for voices that take it. Omit for the voice's default.
  - `assets` object: Page assets (fonts, images) keyed by bundle path.

## Response `200`

The slides are appended and live.
