# SDK retirement

> The Pillow SDKs and SDK audience targeting are retired. Share study links to reach participants.

The Pillow web, iOS, and Android SDKs and SDK audience targeting are retired. SDK integrations must be replaced with shared study links.

You can copy your live study link from **Settings → Integrations** and share it by email, text, or on your website. Add metadata parameters to track where interviews come from.
