• Add an error constant ERROR_INVALID_ENDPOINT which is used then the endpoint option value is not a valid URL


  • Add a license file to the NPM package



  • Fallback endpoint. You can set multiple endpoints; JavaScript agent will try to send the request with the first endpoint, and if the request fails, retry the request with the second endpoint and so on. Supported by all options: scriptUrlPattern, endpoint and tlsEndpoint.
  • Placeholder values for cases where you want to use the default endpoint as a fallback endpoint:


  • A new error is thrown when JS agent is blocked by Content Security Policy: FingerprintJS.ERROR_CSP_BLOCK. JS agent doesn't retry network requests blocked by CSP. In previous versions a common error was thrown in this case: FingerprintJS.ERROR_NETWORK_CONNECTION.


  • Bot Detection agent is embedded into FingerprintJS Pro agent
  • A new fp.get() option products to enable or disable Fingerprint products (Browser Identification, BotDetection)


  • Security improvements


  • Add the zeroTrust field to the TypeScript declaration of JS agent result object



  • fix: JS agent installed from jsDelivr makes a network request to fpnpmcdn.io that can be blocked by your Content Security Policy. This is a temporary fix, it will be reverted. Please switch to our CDN to avoid this problem in future.
