SKAdNetwork raw-data reports

At a glance: SKAdNetwork raw data reports contain row-level data generated after translating and decoding postbacks received by AppsFlyer from iOS, as well as raw SKAdNetwork postbacks. Data is available via Data Locker and Push API. If your subscription plan includes raw data, there is no need for a Data Locker subscription.

Principles:

Data is provided by:
- Data Locker.
  - Note! Available to accounts having a raw data subscription. Meaning, there is no need for a Data Locker subscription. If you aren't currently using Data Locker, the admin must configure Data Locker and enable the SKAdNetwork reports. To do so, go to Integration > Data Locker. Select the SKAdNetwork reports.
  - Data freshness rate: Daily. Data is contained in the h=23 folder of the date the postback is received by AppsFlyer. Example: If the postback was received on Monday, it is processed after the end of the day. Processing is completed, by 12:00 UTC Tuesday, the data is written to the Monday h=23 folder.
- Push API
  - Data freshness: See Push API for SKAdNetwork data.
Install date:
- The install date is derived from the postback arrival time.
- By default, the install time is 48 hours before postback arrival. As such, reports contain installs of multiple days.
- If you use custom conversion value, the formula to derive the install time is:
  postback arrival time-24 hours-hours_from_install.

Report types available are:

Device postback: 1 device postback per install or redownload received from the iOS device.
SKAd raw data:
- AppsFlyer decodes and translates the device postback into raw data records.
- Each postback generates an install or redownload record and in-app event records.
- The number of in-app event records depends on the conversion value (CV) as follows:
  - CV = 0, blank, or null: No in-app records are generated.
  - CV range 1-63: The number of in-app records depends on your measurement settings.

Why are some fields empty? This occurs for any of the following reasons:

Non-mandatory enrichment fields like campaign_name, ad_network_campaign_id, ip that the ad network did not provide.
Apple withheld the data due to Apple threshold policies. Fields like source_app_id, skad_campaign_id, skad_conversion_value.

In-app events

Starting July 21, 2021, there are changes to how we provide in-app event raw data as detailed in the tables.

The number of in-app event records depends on your measurement settings.

Valid for iOS postbacks received starting July 21, 2021
Measurement type	Description
Revenue	Revenue of a given user. If revenue > 0, a record containing the skad_revenue and event_name fields. The fields min_revenue and max_revenue are populated with your custom conversion range values. In most cases, you don't need to consider them.
In-app conversion and funnel events	A record for each unique conversion event performed. The event_name field is populated accordingly. If no events are performed, there is no record. Conversion events have min_event_counter = 0 and max_event_counter = 1.
In-app engagement	To determine the number of times a user performed a given in-app event use the formula`[round up (min_event_counter + max_event_counter) / 2]`

Valid for iOS postbacks received until July 20, 2021.
Measurement type	Number of records	Description
Revenue	0-1	If revenue > 0, a record containing the skad_revenue and event_name fields.
Conversion	0-6	A record for each unique conversion event performed. The event_name field is populated accordingly. If no events are performed, there is no record.
Engagement	0-63	The number of records represents the number of times the user performed the engagement event. If the user does not engage, there are no engagement records.
Custom	0-unlimited	According to your custom conversion schema.

* Derived using the source IP address of the postback sent by iOS ** Apple determines if the field is populated using a privacy threshold mechanism Starting June 2, 2021, the field is added to reports but won't necessarily be populated. Starting July 21, 2021, the field may be populated To determine the number of times a user performs a given in-app event use the formula: `[round up (min_event_counter + max_event_counter) / 2]` . Note! You must round up the nearest integer. Example: A. If min = 0 and max = 1 the average is 0.5; rounding up returns a result of 1. B. If min = 5 and max = 10 the average is 7.5; rounding up returns a result of 8. Revenue is always provided in the field `skad_revenue>`. If you use custom conversion, the bucket range associated with the event and used to calculate skad_revenue is described by min_revenue and max_revenue. In custom conversion, AppsFlyer calculates install time as the postback arrival time - average of min_time_post_install + max_time_post_install.
