# Add Canvas Animations

`POST /canvases/{canvas_ref}/animations`

## Request

- Base URL: `https://api.moda.app/v1`
- URL: `https://api.moda.app/v1/canvases/{canvas_ref}/animations`
- Auth: HTTP bearer

Add preset animations in one atomic batch (order preserved).

``created_ids`` carries the new animation ids in entry order. Presets and
``params`` are validated by the tool host; a rejected entry fails the whole
batch with the typed ``invalid_animation`` error and nothing applied.

## Path parameters

- `canvas_ref` string, required

## Headers

- `Moda-Version` '2026-04-12' | '2026-05-01'

## Request body

- CanvasAddAnimationsRequest
  - `animations` object[], required: Animation entries (nodeId + preset required; optional trigger, durationMs, easing, params). The batch is atomic: one rejected entry applies nothing.
  - `expected_revision` string, nullable: Optional (advisory) — adds are additive.
  - `idempotency_key` string, nullable
