Parameters

Input parameters

If IncludeCustomInputParameters is true in the Verification Result configuration then all non-reserved parameters are bypassed.

Reserved parameters

Session Overrides

Check out the Session Override Configurations section
../verification-configurations/#session-override-configurations

Signature (reSignature)

Check out the Incoming signed Verification Url section
../security/#incoming-signed-verification-url-request-integrity

Expiration (reExpiration)

UTC unix epoch (seconds) at which the signed URL expires. After this timestamp the verification will be rejected with 410 Gone.

Set automatically by the create-signature endpoint when SecuritySettings.ExpirationEnabled is true.

Check out the Incoming signed Verification Url section
../security/#incoming-signed-verification-url-request-integrity

Nonce (reNonce)

One-time-use identifier (GUID without dashes). The first successful session consumes the nonce; further attempts to open the same URL are rejected with 410 Gone.

Set automatically by the create-signature endpoint when SecuritySettings.EnableNonce is true. Nonce requires expiration to be enabled.

../security/#incoming-signed-verification-url-request-integrity

External identifier (reExternalId)

Some face recognition modes require a stable external identifier to link a user across sessions.

  • reExternalId is required when face recognition is configured for:
    • MatchVerification
    • UniqueMatchVerification
  • reExternalId is optional in other modes.

Output parameters

Result URL contract (integration output)

The result redirect URL is the primary integration contract.

  • VerifEye redirects the browser to your configured result URL.
  • The final URL contains query parameters describing the outcome.
  • A signature parameter is appended to enable tamper detection.

The following parameter names are used:

  • reVerificationSessionId
  • reVerificationResult
  • reLivenessResult
  • reFaceRecognitionResult
  • reAgeVerificationResult
  • reGenderVerificationResult
  • reFaceId
  • reAge
  • reGender
  • reCorrelationId
  • reTotalFaceCount
  • reFailedReason
  • reSignature

Parameter presence depends on your project configuration.
