Liverpool.md-apis.medallia.com is a subdomain of Medallia, a well-known customer experience platform. That parent company connection gives this URL some built-in credibility — it's not a random fly-by-night domain. However, the specific page you're looking at doesn't exist. It returns a 404 error, meaning there's nothing to see or interact with right now.
For a typical user, the question "is liverpool.md-apis.medallia.com a scam" probably isn't the right one. More likely, this URL was meant to point to an API endpoint or a developer tool, and it's currently misconfigured or no longer in use. The domain itself is clean: it has a valid SSL certificate, enforces HTTPS, and isn't found on any blacklists.
If you're expecting to find a working website here, double-check the URL for typos or ask the person who sent it to you. There's no evidence of malicious intent, but without content, there's also nothing to evaluate. Reviews of liverpool.md-apis.medallia.com don't exist because there's no service to review. In short, it's safe in the sense that it's not dangerous, but it's also not functional.
