VerifEye Session API Release Notes

Version History

Release Date: 2026-09-03

Configurable face match threshold: the face recognition verifier config now accepts an optional faceMatchThreshold (integer, 0-100, default 80) on verification/create, verification/create-or-update, verification/update and verification/create-session, and returns it from verification/get. Raise it to reject borderline face matches in higher-assurance flows, or keep the default for the balanced operating point. See Verification configurations and the Threshold Reference.

Release Date: 2026-09-02

Emotion and attention: two new optional verifiers reporting nine yes/no signals about the person's expression and gaze at the moment of capture, for your own analytics. They never change a pass or fail. Both carry a surcharge on top of the face check — enabling either applies it, and enabling both does not apply it twice. See Verifier configurations and the Session API reference.
A result value can now be empty: where a verifier did not run, or ran and had no answer, its field is null and its redirect parameter arrives empty (reHappy=) rather than false. Worth checking if your integration treats a missing value as a negative one. See Parameters.
reMatchingUserId and reMatchingVerificationSessionId are reserved. They have been our own result parameters since they were introduced, and are now registered as such — so a custom input parameter of yours using either name is no longer returned in customInputParameters. If you send one, rename it to your own prefix. Full list in Parameters.

Release Date: 2026-07-08

MatchOnlyVerification face recognition mode: the face recognition verifier config now accepts MatchOnlyVerification as a verificationConfig.verifierConfigs.faceRecognition.type. Like MatchVerification, it performs a 1:1 match against the face registered under the provided reExternalId (required), but it never enrolls: if no face is registered under that identifier the verification fails (reFaceRecognitionResult=failed) and stores nothing. Use it for the verify-only side of an enroll-then-verify flow, where reference faces are pre-registered through the Face Recognition API rather than auto-enrolled on first sight.

Release Date: 2026-06-08

Configurable face collection: the face recognition verifier config now accepts a collectionId (verificationConfig.verifierConfigs.faceRecognition.collectionId) on verification/create, verification/create-or-update and verification/update. It is required when face recognition is enabled and must be omitted when its type is Disabled. May only contain letters, numbers, dashes (-), underscores (_) and dots (.), max length 512, and the collection is created automatically if it does not already exist. The value is also returned by verification/get.
