User ID

Foreword

AT Internet’s SDK allows you to choose from three types of user ID in order to track your visitors. You can also choose to use a custom ID. You’ll be able to find this ID in the idclient variable present in hits.

Available identifications

The choice of type of ID to use is first made in the Tag Composer setup interface. It is also possible to modify this parameter directly in your application’s code. The different types are:

UUID uuid

Default – The SDK generates a unique ID (called UUID) for a user when s/he uses the application for the first time. It will then always be used, unless you change the type of ID, or unless the user deletes the application from his/her phone.

Since 2.19.0 SDK version, this identifier is renewed after 13 months by default (editable via UUIDDuration)

IDFV idfv

The SDK recovers this ID provided by iOS. This ID will be the same for the same publisher on a device (e.g. A user downloads two applications from the publisher AT Internet onto his iPhone, the IDFV will be the same on this device.) For the terms of use of this type of ID, please read Apple’s documentation.

IDFA idfa

The Advertising Identifier (IDFA) is a unique ID for each iOS device that mobile ad networks typically use to serve targeted ads.
Users can choose to limit ad tracking by turning off this setting on their devices. (opt-out). To use this option, you have to include the AdSupport.framework framework in your project

With this identification mode, the user will be considered by default as an opt-out and therefore excluded from the analyses if he has activated the limited ad tracking.

Since version 2.12.2, the AT Internet SDK allows you to modify this behavior with the configuration key ignoreLimitedAdTracking. When this configuration is active and the user has enabled limited ad tracking, the identification mode automatically switches to UUID.

Custom ID

With our SDK, you can force the use of a custom type of customer ID.

Limited AdTracking

The use of an advertising identifier (IDFA) is subject to the user’s willingness to disable advertising tracking in which case the user cannot be identified.

By default, if the user activates limited ad tracking, it will be considered as opt-out, and will therefore be excluded from the analyses.

Since version 2.12.2, the AT Internet SDK allows you to modify this behavior using the ignoreLimitedAdTracking configuration key. When this configuration is active and the user has enabled limited ad tracking, the identification mode automatically switches to the UUID type.

Decision tree

Here is a diagram showing the decision tree of the user ID used by the SDK, depending on the configuration.

Tagging examples

1. Selecting UUID as ID type
   • Using the method setConfig()

ATInternet.sharedInstance.defaultTracker.setConfig("identifier", value: "uuid") { (isSet) -> Void in
    print("SDK is now using UUID as visitor identifier")
}

[[ATInternet sharedInstance].defaultTracker setConfig:@"identifier" value:@"uuid" sync:NO completionHandler:^(BOOL isSet) {
    NSLog(@"%@", @"SDK is now using UUID as visitor identifier");
}];

• Using the method setIdentifierType()

ATInternet.sharedInstance.defaultTracker.setIdentifierType(IdentifierTypeKey.uuid) { (isSet) -> Void in
    print("SDK is now using UUID as visitor identifier")
}

ATInternet.sharedInstance.defaultTracker.setConfig("identifier", value: "idfv") { (isSet) -> Void in
    print("SDK is now using IDFV as visitor identifier")
}

[[ATInternet sharedInstance].defaultTracker setConfig:@"identifier" value:@"idfv" sync:NO completionHandler:^(BOOL isSet) {
    NSLog(@"%@", @"SDK is now using IDFV as visitor identifier");
}];

• Using the method setIdentifierType()

ATInternet.sharedInstance.defaultTracker.setIdentifierType(IdentifierTypeKey.idfv) { (isSet) -> Void in
    print("SDK is now using IDFV as visitor identifier")
}

ATInternet.sharedInstance.defaultTracker.setConfig("identifier", value: "idfa") { (isSet) -> Void in
    print("SDK is now using IDFA as visitor identifier")
}

[[ATInternet sharedInstance].defaultTracker setConfig:@"identifier" value:@"idfa" sync:NO completionHandler:^(BOOL isSet) {
    NSLog(@"%@", @"SDK is now using IDFA as visitor identifier");
}];

• Using the method setIdentifierType()

ATInternet.sharedInstance.defaultTracker.setIdentifierType(IdentifierTypeKey.idfa) { (isSet) -> Void in
    print("SDK is now using IDFA as visitor identifier")
}

ATInternet.sharedInstance.defaultTracker.setIgnoreLimitedAdTrackingEnabled(false, sync:true, completionHandler:nil)

[[ATInternet sharedInstance].defaultTracker setIgnoreLimitedAdTrackingEnabled:YES sync:YES completionHandler:nil];

• Selecting a custom ID

ATInternet.sharedInstance.defaultTracker.setParam("idclient", value: "123ABC")

[[ATInternet sharedInstance].defaultTracker setStringParam:@"idclient" value:@"123ABC"];
