  title: Fingerprint Server API
  description: >-
    The Fingerprint Server API lets you get, search, update, and delete
    identification Events and Visitors in a server environment. Each event
    carries device attributes and the enabled Smart Signals (bot, VPN, proxy,
    Tor, IP blocklist, tampering, virtual machine, incognito, emulator, root,
    jailbreak, Frida, cloned app, factory reset, velocity). Requests are
    authenticated with the `Auth-API-Key` header carrying your workspace Secret
    API Key. The API is served from regional hosts; use the host that matches
    your workspace region (Global, EU, or Asia). The product also exposes a
    Related Visitors endpoint and Webhooks that POST the same event payload to a
    configured endpoint.
