FaceAuthenticator
To use Sdk, you can either remotely import the
.js
file or download it locally.Include the
.js
file directly from the CDN:<script src="https://repo.combateafraude.com/javascript/release/face-authenticator/<VERSION>.zip" type="text/javascript"></script>
You can retrieve the class from the SDK using the following code:
const sdk = window['FacesSDK'];
The SDK has an isolated initialization method, to allow greater control over when it occurs.
During this process, 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.

To perform integration through an iframe, camera and fullscreen permissions must be provided.
<iframe
src="https://caf.example"
allow="camera;fullscreen;accelerometer;gyroscope;magnetometer;"
></iframe>
To use the SDK through a Webview, camera permission must be granted in your native application.
Example implementation on Android.
AndroidManifest.xml
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature
android:name="android.hardware.camera"
android:required="true" />
MainActivity
@Override
public void onPermissionRequest(final PermissionRequest request) {
request.grant(request.getResources());
}
The 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.
await facesSdk.execute();
Field | Type | Description |
signedResponse | string | Signed response from the CAF server confirming that the captured selfie has a real face. This parameter is used to get an extra layer of security, checking that the signature of the response is not broken, or caused by request interception. If it is broken, there is a strong indication of request interception. |

Event | Description |
requestId | Request identifier. |
isAlive | Validation of a living person, identifies whether the user passed successfully or not. |
isMatch | Face match validation result. |
token | Request token. |
userId | User identifier provided for the request. |
imageUrl | Temporary link to the image, generated by our API. |
personId | User identifier provided for the SDK. |
sdkVersion | Sdk version in use. |
iat | Token expiration. |
message | Return message. |
The isAlive parameter is VERY IMPORTANT, based on it validation must be carried out to continue with the flow or not, in the case of
isAlive: true
your user can continue with the journey, in the case of isAlive: false
, this user is not valid and should be barred from the rest of the journey. Furthermore, the isMatch parameter indicates whether the Face Match passed successfully or not, returning isMatch: true
in case of success and false
in case of failure.Currently the SDK emits three types of events:
Event | Description |
started | Capture stream initialization. |
sdk-button-ready | SDK components have been loaded and ready to use. |
passed | Image capture was successful. |
failed | Image capture failed. |
error | An error occurred during the capture process. |
streaming | streaming started, full screen start. |
streamed | End of streaming, closing full screen. |
cancelled | Capture flow cancellation. |
permission | Camera permission is requested. |
permission_denied | Camera permission was denied. |
unsupported | Browser does not support Sdk. |
