User ID

  • iOS
  • watchOS
  • tvOS


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.


Get off to a good start

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

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.

  • 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

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

  • Custom ID

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