Set up App Tracking Transparency

If you want to record the device’s ID for Advertisers (IDFA), you must display a prompt to get your user’s authorization. To do this, you need to include Apple’s App Tracking Transparency (ATT) framework in your app. The Adjust SDK stores the user’s authorization status and sends it to Adjust’s servers with each request.

Authorization statuses

ATT authorization wrapper

public static void RequestAppTrackingAuthorization(Action<int> callback)

The Adjust SDK contains a wrapper around Apple’s requestTrackingAuthorizationWithCompletionHandler method. You can use this wrapper if you don’t want to customize the ATT prompt.

The callback method triggers when your user responds to the consent dialog. This method sends the user’s consent status code to Adjust’s servers. You can define responses to each status code within the callback function.

You must specify text content for the ATT. To do this, add your text to the NSUserTrackingUsageDescription key in your Info.plist file.

1
Adjust.RequestAppTrackingAuthorization((status) =>
2
{
3
    switch (status)
4
    {
5
        case 0:
6
            // ATTrackingManagerAuthorizationStatusNotDetermined case
7
            break;
8
        case 1:
9
            // ATTrackingManagerAuthorizationStatusRestricted case
10
            break;
11
        case 2:
12
            // ATTrackingManagerAuthorizationStatusDenied case
13
            break;
14
        case 3:
15
            // ATTrackingManagerAuthorizationStatusAuthorized case
16
            break;
17
    }
18
});

Example

This example shows how to log a human-readable description of the user’s authorization status when they interact with a prompt.

1
Adjust.RequestAppTrackingAuthorization((status) =>
2
{
3

4
    switch (status)
5
    {
6
        case 0:
7
            Debug.Log("The user hasn't responded to the access prompt yet.");
8
            break;
9
        case 1:
10
            Debug.Log("Access to app-related data is blocked at the device level.");
11
            break;
12
        case 2:
13
            Debug.Log("The user has denied access to app-related data for device measurement.");
14
            break;
15
        case 3:
16
            Debug.Log("The user has approved access to app-related data for device measurement.");
17
            break;
18
    }
19
});

Get current authorization status

public static int GetAppTrackingAuthorizationStatus()

You can retrieve a user’s current authorization status at any time. Call the GetAppTrackingAuthorizationStatus method to return the authorization status code as an int.

1
Adjust.GetAppTrackingAuthorizationStatus();

Custom prompt timing

public int? AttConsentWaitingInterval { get; set; }

If your app includes an onboarding process or a tutorial, you may want to delay sending your user’s ATT consent status until after the user has completed this process. To do this, you can set the AttConsentWaitingInterval property to delay the sending of data for up to 360 seconds to give the user time to complete the initial onboarding. After the timeout ends or the user sets their consent status, the SDK sends all information it has recorded during the delay to Adjust’s servers along with the user’s consent status.

1
AdjustConfig adjustConfig = new AdjustConfig("{YourAppToken}", AdjustEnvironment.Sandbox);
2
//...
3
adjustConfig.AttConsentWaitingInterval = 30;
4
//...
5
Adjust.InitSdk(adjustConfig);
