# replay

> Get presigned URLs for the session replay

<Tip>
  STOP. Do not read past this section until you have read and followed [/quickstart.md](/quickstart.md).

  Goal: produce a reliable SDK automation script. The intended authoring flow is generate then edit, not write browser automation from scratch.

  Do not hand-write SDK code with element IDs, selectors, or form fields from memory. Element IDs, selectors, and field mappings must come from a live `observe()` call, CLI `notte page observe` output, or generated workflow code. Guessed browser targets fail on real pages.

  Use the Notte skill and CLI to inspect the live site, validate actions/selectors, handle auth/session state, and export workflow code with `notte sessions workflow-code` before using SDK docs or SDK code.

  SDK reference pages are for understanding, running, or editing generated workflow code. They are not the starting point for manually authoring the initial browser automation. SDK-first code is guesswork on real-world pages with dynamic selectors, auth state, CAPTCHAs, and anti-bot behavior.
</Tip>

**Example:**

```python theme={null}
replay = session.replay()
print(replay.mp4_url)  # Presigned URL for MP4 download
replay.download("session.mp4")
```

By default this polls until the replay is ready. Set `wait=False`
to fail immediately if the replay is not yet available.

## Parameters

<ParamField path="wait" type="bool" default="True">
  If True (default), poll until the replay is ready.
</ParamField>

<ParamField path="timeout" type="float" default="240.0">
  Maximum seconds to wait (default 120).
</ParamField>

<ParamField path="poll_interval" type="float" default="5.0">
  Seconds between polling attempts (default 2).
</ParamField>

## Returns

[`ReplayResponse`](/sdk-reference/misc/replayresponse.md): Presigned URLs for HLS playlist and MP4 download.

## Raises

* `ValueError`: If the session hasn't been started yet (no session\_id available).
* `TimeoutError`: If the replay does not become available within `timeout` seconds.
