Headers

Key	Type	Notes	Description
App-ID	String	Required	Application ID that generated from Application Menu in Verihubs Client Dashboard. To hit in Testing and Live mode you need a Production Application ID.

Body Parameters

Parameter	Type	Notes	Default	Description
image	String	Required	-	A base64 or URL image file. Image Type JPEG, JPG, PNG. Max File size: 5MB. Recommended image ratio 4:3. If the photo is not a face image, it will return "face not detected".
subject_id	String	optional	-	A unique key to set the id of image. When subject_id is already exists, the enroll method will work as "update" method
is_quality	boolean	optional	true	Determines whether Image Quality (blur and dark) will be computed and return as result
is_attribute	boolean	optional	true	Determines whether Image Attribute (sunglasses, mask, veil, hat, and face blocker object) will be detected and return as result
is_liveness	boolean	optional	true	Determines whether Passive Liveness will be computed and return as result
validate_quality	boolean	optional	false	Determines whether Quality validation will be executed. The validation consists of checking blur and dark. "validate_quality" can be TRUE only when "is_quality" is TRUE.
validate_attribute	boolean	optional	false	Determines whether Attribute validation will be executed. The validation consists of checking whether sunglasses, mask, or face blocker is detected in the input image. "validate_attribute" can be TRUE only when "is_attribute" is TRUE.
validate_liveness	boolean	optional	false	Determines whether Liveness validation will be executed. The validation checks whether input image is live / spoof. "validate_liveness" can be TRUE only when "is_liveness" is TRUE.
validate_nface	boolean	optional	false	Determines whether the number of faces validation will be executed. The validation checks whether the input image consists of more than one face.
threshold	string	optional	"moderate"	threshold can be selected based on security level: "BASIC", "MODERATE", "HIGH"
