Fingerprint Lookup

GEThttps://telemetry.stytch.com/v1/fingerprint/lookup

Lookup the associated fingerprint to the telemetry ID returned from the GetTelemetryID. Learn more about the different fingerprint types and verdicts in our DFP guide.

Make a decision based on the returned verdict:

  • ALLOW - This is a known valid device grouping or device profile that is part of the default ALLOW listed set of known devices by Stytch. This grouping is made up of verified device profiles that match the characteristics of known/authentic traffic origins.
  • BLOCK - This is a known bad or malicious device profile that is undesirable and should be blocked from completing the privileged action in question.
  • CHALLENGE - This is an unknown or potentially malicious device that should be put through increased friction such as 2FA or other forms of extended user verification before allowing the privileged action to proceed.
