FaceAuthenticator (Deprecated)

Importing SDK
To use FaceAuthenticator, you can either remotely import the .js file or download it locally.
Remotely
Include the .js file directly from the CDN:
<script src="https://repo.combateafraude.com/javascript/release/face-authenticator-deprecated/<VERSION>.umd.js" type="text/javascript"></script>
You can retrieve the class from the SDK using the following code:
const { FaceAuthenticatorSdk } = window['@combateafraude/face-authenticator'];
Locally
Download the .js file and import it as an ES6 module:
import { FaceAuthenticatorSdk } from '../assets/js/face-authenticator-<VERSION>.js'
Construction
In the builder, the SDK receives a single parameter with the settings:
const sdk = new DocumentDetectorSdk(options);
Supported parameters

* Advanced capture consists of using more complex and not-so-stable APIs in browsers that support them (e.g. ImageCapture)
​
Example
const sdk = new DocumentDetectorSdk({
    token: `my-sdk-token`,
    language: `pt_BR`,
​
    analyticsSettings: {
      disableAnalytics: false,
      trackingId: "",
      trackingInfo: "",
    },
​
    environmentSettings: {
        disableDesktopExecution: false,
    },
​
​
    appearenceSettings: {
        hideCaptureTitle: false,
        hideCaptureMask: false,
        hideCameraSwitchButton: false,
        useGenericMask: false,
    },
​
    capturerSettings: {
        disableAdvancedCapturing: false,
    },
​
    textSettings: {
        messages: {
            processMessage: '',
            wrongDocumentMessage: '',
            bothWrongSideMessage: '',
            wrongSideMessage: '',
            lowQualityMessage: '',
            captureFailedMessage: '',
        }
});
​
CaptureStage
CaptureStage allows the client to configure the stages. To do this, we offer the CaptureStage object, where you can set the following parameters:
Parameter
mode
Desired capture mode. It can be used manual, automatic or upload. In the manual capture, a button will be enabled for the user to do the capture, in the upload, the functionality of uploading documents will be displayed instead of capturing.
attempts
The number of attempts of the current stage. If it is the only stage, the value 0 must be passed.
duration
Duration time of the current stage. If more than one stage is set, the total time for each stage can be set, and when the total time is reached, the stage will move on to the next one. Set it to 0 if you don't want to set a time for the stage.
Example CaptureStage
const stages = [
  { mode: "automatic", attempts: 3, duration: 60 },
  { mode: "manual", attempts: 3, duration: 60 },
  { mode: "upload", attempts: 0, duration: 0 },
];
Initialization
initialize(): Promise<void>
The SDK has a separate method of initialization, to allow greater control over when it occurs.
During this initialization, the SDK will initialize its internal variables and download the resources it needs to run.
[!] You must call this method before using other SDK methods.
[!] The initialization of the SDK can take a few seconds. We recommend that you call this function as early as possible in your flow so that opening the SDK is smooth for the user.
Example
await sdk.initialize();
Utilization
Opening and taking selfies
capture(container: HTMLElement, stages, {personData?: PersonData, totalAttempts?: Number}): Promise<Result>
Method used to load the SDK onto the screen and perform selfie capture.
It will initialize the video stream (requesting permissions if needed) and load it into the container.
Parameters
Parameter
Type
personData.cpf
CPF of the user doing the authentication (required).
string
personData.name
Name of the user doing the authentication (optional).
string
¹ If not specified, automatic capture is used.
² If not specified, a default value of 30 seconds is used.
Example
// div or another element on DOM
const sdkContainer = document.getElementById('sdk-displayer');
const personData = { cpf: 'user-cpf', name: 'user-name' };
await sdk.capture(sdkContainer, stages, {personData, totalAttempts});
Return
The return consists of an object with the following fields:
Field
Type
Description
requestId
string
Unique identifier of the requisition
isMatch
boolean
Boolean indicating whether the captured face is identical to the face registered for the entered peopleId
peopleId
string
Information of the document reported for authentication
openEyesProbability
number
Probability of eyes being open in captured selfie
Close SDK
close(): Promise<void>
The method used to remove the SDK on the screen.
De-initialize the SDK
dispose(): Promise<void>
The method used to remove the SDK on the screen.
Will de-initialize the video stream and clear the SDK's internal variables
Complete Example
Soon.
