Analytics

The SDK offers a callback function that you can implement, which the SDK will then use to send events.

onTrace: (trace) => {
  console.debug("trace callback function ", trace);
}

Trace is the object passed to your callback function and you can use it with any of your analytics tools or any custom tracing mechanism.

Trace is the object passed to your callback function and has the following properties (see index.d.ts of the SDK module for details):

Property	Type	Optional	Default	Description
sessionId	String	No	None	Session id (UUID v4) created by the SDK or passed by your application
category	TraceCategory	No	None	See below
event	TraceEvent	No	None	See below
status	TraceStatus	No	None	See below
page	TracePage	Yes	null	See below
statusCode	TraceStatusCode	Yes	null	See below
statusMessage	String	Yes	null	Description of the status code if any
documentType	DocumentType	Yes	null	Document type
timestamp	Date	No	Timestamp of the event	Timestamp of the event

TraceCategory has the following properties:

Property	Type	Description
ENROLLMENT	Enum String	For events related to the enrollment flow
FACE_SESSION	Enum String	For events related to the face session flow

TraceEvent has following properties:

Property	Type	Description
VIEW	Enum String	Event when a screen is presented to the user. Can be used to track the screen sessions.
START	Enum String	Event when a certain process starts, e.g. scanning of a document starts
IN_PROGRESS	Enum String	Event during document scanning and facial recognition
COMPLETE	Enum String	Event when any process completes, e.g. scanning of a document completes
SKIP	Enum String	Event when a specific step is skipped. Only available in the background check step when the view is enabled, consent is enabled the the enduser declines the consent

FAILURE	Enum String	Status when an event is not successful

TracePage has following properties:

Property	Type	Description
SCAN	Enum String	Document scanning page
FACE	Enum String	Facial recognition page
BACKGROUND_CHECK	Enum String	Background check page

TraceStatusCode has the following properties:

Note: Please be aware that all codes with event IN_PROGRESS, except for SCAN_DOCUMENT_FRONT_PROCESSED and SCAN_DOCUMENT_BACK_PROCESSED, are throttled (limited to one identical event every 5 seconds). This is to ensure that your client is not overwhelmed and to accommodate varying speeds of different devices, which may send different numbers of events.

Property	Type	Description
USER_CANCEL	Enum String	Status defined when user cancels the flow, or user declines the background check or users stops the chip reading process (only iOS)

FACE_INCORRECT_DISTANCE_DETECTED	Enum String	Incorrect face distance detected
