About face_token

Face Detection can detect all the faces within the image. Each detected face gets its face_token, which can be used in follow-up analysis and operations.

If you want to use the detected face for follow-up operations, we recommend you add its corresponding face_token into FaceSet. A face_token expires within 72 hours if it is not added into any FaceSet. 

Every time you operate face detection upon one image, the face within the image will get a different face_token.
