These values have a maximum length of 512 characters. ### Application Ad Click #### WT.a_ac `WT.a_ac=1` Indicates that an ad was clicked within a mobile application. ### Application Ad Impression #### WT.a_ai `WT.a_ai=1` Indicates that one or more ads was viewed in a mobile application. Typically, this parameter is used with the `WT.a_an` parameter to specify one or more ads viewed in a single application screen. ### Application Ad Name #### WT.a_an `WT.a_an=Name[;...]` Specifies one more names of ads presented in a mobile application. You can pass multiple ad names using semicolons to delimit the list. The maximum length for each *`Name`* is 64 bytes. ### Application Name #### WT.a_nm `WT.a_nm=application name` Specifies the name of a mobile application. This parameter can be used to report on the usage of different applications. ### Application Category #### WT.a_cat `WT.a_cat=application category` Specifies a category of mobile application such as Games, Health & Wellness, or Productivity. This parameter can be used to report on the usage of different types of apps. ### Application Publisher #### WT.a_pub `WT.a_pub=application publisher` Specifies the developer, publisher, or vendor for an application. This parameter is required. ### Connection Type #### WT.ct `WT.ct=connectionType` Specifies the connection type used to send the data. Many mobile devices go in and out of various connection states such as wifi, 3G, Edge, or 7.1G. To avoid sending a flood of this data as the connection fluctuates, the best practice is to send this parameter only once per session. The Webtrends Mobile Application Libraries use this best practice. ### Country #### WT.g_co `WT.g_co=Country Code` Specifies the country of origin for mobile traffic using a country code. ### Device Model #### WT.dm `WT.dm=device model` Specifies the model of the mobile device that an application is running on, for example the model of a mobile phone. For example, `WT.dm=Motorola Droid` or `WT.dm=iPhone 3GS`. ### Event Time Stamp #### WT.ets `WT.ets=epoch time stamp` Specifies an epoch (unix) time stamp for an event. This time stamp is recorded so events that occur when a device is offline can be sent as an ordered batch when the device comes back online. For example, `WT.ets=1006725234`. ### Event Type #### WT.ev `WT.ev=eventType` Specifies the type of event activity on a mobile device. For example, this parameter can be used to differentiate activities such as clicks, swipes, and content views. ### Geolocation Coordinates #### WT.gc `WT.gc=latitude,longitude` Specifies the latitude and longitude of a mobile device.
