Analytics

The SDK provides an interface that you can implement and that will be used by the SDK to send events. The interface is simply the one below:

@interface UQTracer : NSObject
- (void)trace:(UQTrace *)trace;
@end

Trace is the object passed to your implementation and you can use it with any of your analytics tools or any custom tracing mechanism. Make sure to avoid blocking calls if you push the information of the trace object to any external system.

The UQTrace object has the following properties:

Property	Type	Optional	Default
deviceIdentifier	String	No	None	This value uniquely identifies multiple sessions from a given device (persisting until the app is reinstalled)
sessionId	String	No	None	Session id (UUID v4) created by the SDK or passed by your application
category	UQTraceCategory	No	None	See below
event	UQTraceEvent	No	None	See below
status	UQTraceStatus	No	None	See below
page	UQTracePage	Yes	null	See below
statusCode	UQTraceStatusCode	Yes	null	See below
statusMessage	String	Yes	null	Description of the status code if any
documentType	DocumentTypeID	Yes	null	Document type id
timestamp	Date	No	Current date	Timestamp of the event
deviceIdentifier	UUID	No	None	This value uniquely identifies all sessions from a given device (persisting until the app is reinstalled). You may still use more specific identifiers, such as phone number or email, if you already know the user. Available from SDK version 3.4.1 and above.

UQTraceCategory has the following properties:

Property	Type	Description
Property	Type	Description
TC_SDK	Enum String	For SDK level events e.g. after has successfully initialized
TC_ENROLLMENT	Enum String	For events related to the enrolment flow
TC_LOOKUP	Enum String	For events related to the lookup flow
TC_FACE_SESSION	Enum String	For events related to the face session flow

UQTraceEvent has following properties:

Property	Type	Description
TE_INIT	Enum String	Event when SDK initializes
TE_VIEW	Enum String	Event when a screen is presented to the user. Can be used to track the screen sessions.
TE_START	Enum String	Event when a certain process starts, e.g. scanning of a document starts
TE_IN_PROGRESS	Enum String	Event during document scanning and facial recognition
TE_COMPLETE	Enum String	Event when any process completes, e.g. scanning of a document completes
TE_SKIP	Enum String	Event when a specific step is skipped, e.g. NFC
TE_FINISH	Enum String	Event when the the overall flow is terminated

UQTraceStatus has the following parameters:

Property	Type	Description
TS_SUCCESS	Enum String	Status when an event is successful
TS_FAILURE	Enum String	Status when an event is not successful

UQTracePage has following properties:

Property	Type	Description
TP_SCAN	Enum String	Document scanning page
TP_LOOKUP	Enum String	Lookup page
TP_READ	Enum String	NFC chip reading page
TP_FACE	Enum String	Facial recognition page

UQTraceStatusCode 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 phones, which may send different numbers of events.

Property	Type	Description
TSC_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)

To enable the tracing mechanism, pass your implementation to the init method like the example below. Even in a Swift project you have to write the implementation in Objective-C. You can then decide to follow up with Swift passing the trace data from objective c to Swift.

Tracer implementation example:

Objective-C

@implementation UQTracer

- (void)trace:(UQTrace *)trace {
    NSString *documentTypeName = @"";
    if (trace.documentType != UNSPECIFY) {
        UQDocumentConfig *document = [[UQDocumentConfig alloc] initWithDocumentType:trace.documentType];
        documentTypeName = document.documentName;
    }
    NSString *timeStamp = [self timeStamp:trace.timestamp];
    NSLog(@"Trace(sessionId=%@, category=%@, event=%@, page=%@, status=%@, statusCode=%@, statusMessage=%@, documentType=%@, timestamp=%@)" , trace.sessionId, trace.category->name, trace.event->name, trace.page->name ,trace.status->name, trace.statusCode->name, trace.statusMessage, documentTypeName, timeStamp);
}

- (NSString *)timeStamp:(NSDate *)currentDate {
    return [NSDateFormatter localizedStringFromDate:currentDate
                                            dateStyle:NSDateFormatterFullStyle
                                            timeStyle:NSDateFormatterFullStyle];
}
@end

Tracer implementation example passing the trace data to Swift (the example below assumes that you have the SwiftTracer object defined in your Swift project with method signature trace):

Objective-C

@interface UQTracer ()
@property (nonatomic) SwiftTracer *swiftTracer;
@end

@implementation UQTracer
- (instancetype)init {
    self = [super init];
    if (self) {
        self.swiftTracer = [[SwiftTracer alloc] init];
    }
    return self;
}

- (void)trace:(UQTrace *)trace {
    NSString *documentTypeName = @"";
    if (trace.documentType != UNSPECIFY) {
        UQDocumentConfig *document = [[UQDocumentConfig alloc] initWithDocumentType:trace.documentType];
        documentTypeName = document.documentName;
    }

    [self.swiftTracer     traceWithSessionId:trace.sessionId
                                    category:trace.category->name
                                       event:trace.event->name
                                      status:trace.status->name
                                        page:trace.page->name
                                  statusCode:trace.statusCode->name
                               statusMessage:trace.statusMessage
                                    document:documentTypeName
                                   timestamp:trace.timestamp];
}
@end

Initialize SDK with tracer in Objective-C:

Objective-c

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary<UIApplicationLaunchOptionsKey,id> *)launchOptions {
    UQTracer *tracer = [[UQTracer alloc] init];
    [[UQBuilderController alloc] initWithTracer:tracer];
    return YES;
}
@end

Initialize SDK with tracer in Swift:

Swift

class AppDelegate: UIResponder, UIApplicationDelegate {
        
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        let tracer = UQTracer()
        _ = UQBuilderController.init(tracer: tracer)
        return true
    }
}

Below you can find an example of the tracing above for a full enrollment flow with some errors in between to showcase the events:

Below you can find an example on how to use the trace information with Firebase Analytics:

Objective-C

#import <Foundation/Foundation.h>
#import <UqudoSDK/UqudoSDK.h>
@import FirebaseAnalytics;

@implementation UQTracer

    [parameters setValue:timeStamp forKey:@"timestamp"];
    if (trace.sessionId) {

    }
    if (TP_NULL != trace.page) {
        [parameters setValue:trace.page->name forKey:@"page"];
    }
    if (TSC_NULL != trace.statusCode) {
        [parameters setValue:trace.statusCode->name forKey:@"statusCode"];
    }
    if (trace.documentType != UNSPECIFY) {
        UQDocumentConfig *document = [[UQDocumentConfig alloc] initWithDocumentType:trace.documentType];
        [parameters setValue:document.documentName forKey:@"documentType"];
    }
    if (trace.statusMessage) {

    }
    [FIRAnalytics logEventWithName:trace.category->name parameters:parameters];
}

- (NSString *)timeStamp:(NSDate *)currentDate {
