This reference lists Autocapture event types and event property names for web when you use the [Browser SDK 2](/docs/sdks/analytics/browser/browser-sdk-2). Use it when you need a stable contract for pipelines, partners, or validation.

For Autocapture setup steps, go to [Autocapture](/docs/get-started/autocapture). For full property descriptions with examples, go to [Autocapture events and properties](/docs/data/autocapture-events-and-properties). For native iOS and Android Autocapture event properties, go to [Mobile Autocapture Schema](/docs/data/mobile-autocapture-schema).

## Machine-readable schema

Download the schema as JSON: [`/docs/web-autocapture-schema.json`](/docs/web-autocapture-schema.json).

## Shared conventions

- **Event type** values match what Amplitude stores as `event_type` (for example, `Page viewed`).
- Web event types don't use the `[Amplitude]` prefix, except for `[Amplitude] Network Request`.
- **Property names** appear in Amplitude exactly as listed here.
- Session events carry no additional properties beyond standard user and session context.

## Web (Browser SDK 2)

Configure which events Amplitude captures through `AutocaptureOptions` in the Browser SDK 2. Go to [Autocapture (Browser SDK 2)](/docs/sdks/analytics/browser/browser-sdk-2#autocapture) for configuration options.
