## Onboarding / API

### Added sandbox support for Smart populate website lookups

`POST /v1/prefill/businesses` with `website_url` returns a business profile in sandbox instead of `null`. Sandbox derives the business from the submitted domain, so any domain returns a usable profile, and a domain that maps to a sandbox test business returns that business. `industry_classifications` is `null` unless the account uses enhanced sandbox data. Integrations can exercise the website lookup path before moving to Production. Production behavior is unchanged. [View the Smart populate guide](/accelerate-onboarding/smart-populate).

## Web Presence / API

### Added X profiles to web presence results

Web presence analysis discovers and matches X (formerly Twitter) profiles and returns them in the `profiles` array on the business with `type` set to `x`. Sandbox returns an X profile alongside the other supported platforms. Integrations that branch on `profile.type` should tolerate the new value. [View the Profile object reference](/reference/profile).
