Registration

Before using the Facial Validation API feature, it is necessary to register the client. This action will generate an initial entry in the database that will provide an image to be used as a base during validation.

Object Definition

Request Body

{        
    "registration_key": "ee37510e-4dfe-4b9c-b1f4-667288de2190",
    "document_number": "123.456.789-00",
    "image": {
        "image_key": "f1c0d2e1-f950-4360-896d-36588e443fc9",
        "file_size": 47407,
        "width_px": 0,
        "height_px": 0,
        "created_at": "2020-07-29T18:40:57Z",
    },
    "status": "indeterminate",
    "registration_status_events": [],
    "registration_date": "2020-07-29T18:40:57Z"
} 

When registering a client, our API will generate a JSON object containing all information related to this registration. This object will be used as a reference when performing facial recognition of this client before a transaction.

name	type	description
registration_key	string	Registration object key
document_number	string	Client's CPF
image	image	Object that carries the properties of the image sent in registration
status	string	Client registration status
registration_status_events	registration_status_events	Object that carries the registration status modification history
registration_date	datetime	Registration date in UTC

Status Dynamics - status

Once a client is registered, the status of this registration will be returned under the status flag. The possible results are:

Result	Description
authentic	This registration has a history of successfully completed transactions
undefined	This registration has no fraud history nor history of successfully completed transactions
fraud	This registration has associated fraud history

Creating a Registration

Request Body: Simultaneous image submission (Base64)

{
    "document_number": "123.456.789-00",
    "image": "base_64_image_code",
}

Request Body: Prior image submission

{
    "document_number": "123.456.789-00",
    "image_key": "f1c0d2e1-f950-4360-896d-36588e443fc9",
}

To register a client, simply send a registration JSON object with a POST request to the endpoint:

https://api.caas.qitech.app/face_recognition/registration

Two types of registration JSON objects are supported. One in case of prior image submission through the /image endpoint, and another in case of simultaneous image submission with the registration request.

name	type	description
document_number	String	Client's CPF
image	String	Image Base64 without headers or additional information
image_key	String	UUID4 returned during image submission by the /image endpoint

After submission, a Registration object containing the user registration data will be returned.

Attention - When performing simultaneous image submission with registration, it will be submitted to the same quality tests executed when the image is sent through the /image endpoint. Thus, the sent image is subject to the same rules described in the Image section of this documentation.

Status Update - status

Request Body

{
    "registration_status": "fraud",
    "incident": "misappropriation",
    "event_date": "2029-08-25T13:34:12-03:00"                  
}

To ensure feedback to the fraud database, it is necessary to inform the system if a client commits any type of fraud or if the client completes their first transaction successfully.

For this, updating a client's registration status as a fraudster should be sent as a PUT request to the endpoint:

https://api.caas.qitech.app/face_recognition/registration/{registration_key}/status

The following values can be used in the incident field, which indicates the type of fraud committed by the client:

Enumerator	Description
misappropriation	Individual performed misappropriation of some product
misrepresentation	Individual registered under false or third-party documents
successfull_transaction	Individual completed a transaction successfully
status_restoration	Enumerator used in cases where it is desired to restore the status to undefined
