Raw data field dictionary

For:
Marketers Developers
Last update:

At a glance: The data field dictionary (raw data specification) describes field contents. It should be used to help you understand what fields mean, how they are formatted, and when they are available.

Raw data field dictionary 

The following table is a dictionary that lists the raw data fields available in various AppsFlyer reports The table is consistently being updated as additional raw data fields are added in AppsFlyer.

The columns in the dictionary table are: 

  • Field group: Logical grouping based on field use. Note! Fields in the ad revenue group are displayed in raw data reports either as their own columns or populated as part of the Event value.  
  • Field Name:
    • Field name used in reports provided via the Export page and Pull API.
    • The notation [n] means that there are multiple instances of the same field, the difference being the instance number. For example, Sub Param [n] means, Sub Param 1, Sub Param 2, ..., Sub Param 5. The range of n values is noted as (n=1-5). 
  • API name: 
    • Field name as it displays in Data Locker and Push API reports.
    • The notation [n] means that there are multiple instances of the same field, the difference being the instance number. For example, Sub Param [n] means, Sub Param 1, Sub Param 2, ..., Sub Param 5. The range of n values is noted as (n=1-5). 
  • Source: The original source location of the field content, for example:
  • Description
    • Some fields have different meanings depending on the context of the event, for example as a result of a UA or retargeting campaign.
  • Format: Field type and length.
    • String: The maximum length of the string. We don't recommend exceeding 1024 characters in length or the field length limitations found here.
    • Date time: 
      • String with the format, yyyy-mm-dd hh:mm:ss. For example, 2019-09-17 00:09:25 The time zone used to display the data depends on the data delivery tool as follows:
        • Export data page: app-selected time zone.
        • Push API: time fields have a selected_time_zone option which means app-specific time zone otherwise UTC.
        • Master API: Default is the app-selectable time zone.
        • Data Locker: UTC
      • Date fields in the CSV files have the format yyyy-mm-dd. When you open a CSV file in Excel, date fields are formatted using the computer's date and time settings. You can change the display format in Excel. To see the unformatted value, open the file using an editor.
      • Push API:
        • For timestamp fields in UTC: format yyyy-mm-dd hh:mm:ss.sss. For example, 2019-09-17 00:09:25.123 
        • For timestamp fields in the selected time zone: format yyyy-mm-dd hh:mm:ss.sss±th:tm. For example 2019-01-20 04:51:16.000+0000
    • Enum n char: Enum fields can only contain specific values. For example, cost currency has 3 characters and can contain only currency codes as specified
    • Enum 5 char boolean: The value of the field can be either TRUE or FALSE

 Tip

  • To sort the table, click on a column name.
  • You can also download the table.
  • The downloaded CSV contains additional fields to those mentioned above:
    • Part of main AppsFlyer report schema:
      • The majority of AppsFlyer reports are built from the same schema and contain the same fields.
      • Some fields, may be populated with null or empty values, depending on the report, and whether the data is collected from ad networks, advertisers, device platforms, etc. 
      • When configuring your BI systems, it's best to configure all main AppsFlyer schema fields, even if a given report always returns them as null or empty values. This enables you to easily ingest the data if and when it becomes available. 
      • If a field is not part of the main AppsFlyer report schema, it's only contained in specific reports. For example, SKAN reports.
    • Report delivery method: Indicates whether a given field is available via Push API, Export data/Pull API, and Data Locker. Note: Even if a field is part of the main AppsFlyer report schema, it may not be part of reports delivered by a specific method. For example, the placement field is part of the main AppsFlyer schema, but it only displays in reports delivered via Data Locker, Pull API, or the Export data page; not via Push API.
