# GET /api/builder/preview/exchange/{token}/

`GET /api/builder/preview/exchange/{token}/`

## Request

- Base URL: `https://api.baserow.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.baserow.io/api/builder/preview/exchange/{token}/`
- Auth: none required

Consume the preview pass, set a session cookie, and redirect the browser.

Invalid or expired tokens return ``404`` without creating a cookie. The
requested redirect is accepted only when it points to the configured
preview website; otherwise a safe preview root URL is used. Cookie
security flags are selected according to whether the backend and
preview website are considered the same browser site.
