Call parameters

Parameter	Value	Mandatory
api_token	An admin needs to retrieve the token. To retrieve the API token, click your email > API Tokens.	Yes
app_id	App identifier, as found in AppsFlyer. Insert the app ID exactly as found in AppsFlyer Prefix iOS apps with id Use app_id=all to query for all your apps	Yes
from	Lower bound of the LTV attribution date range. Format: String yyyy-mm-dd Example: from: 2020-01-02	Yes
to	Higher bound of the LTV attribution date range Number of the days in the range: 1-31 days For a single day: from and to values are identical.  Format: yyyy-mm-dd Example: from: 2021-01-01, to: 2021-01-31 is 31 days.	Yes
groupings	Group by parameters, separated by a comma. See the Groupings table for the list available  Example: groupings=pid,geo	Yes
kpis	List of KPIs to include, each separated by a comma. See the KPI table that follows for a list of KPIs. Example: kpis=installs,clicks, impressions,sessions,retention_day_7	Yes
filters	Data can be filtered using one or more filter options.	No
currency	To return data using the app-specific currency set currency=preferred	No
timezone	To return data using the app-specific time zone set timezone=preferred.  See localization rules.	No
format	By default, the response data is received in CSV file format. If you prefer to get the data in JSON format append &format=json to the URI	No

These dimensions are used for collecting the data into groups to allow easier and more accurate examination of the information. You can find descriptions of these fields here.

KPIs are the metrics used for gaining an insight into the behavior of your app. The KPIs are grouped by type in the tabs that follow. 

Calculated KPIs

In addition, to the KPIs described previously, you can add calculated KPIs to your master API reports. This enables you to have your own calculated reports included in your Master API reports.

You can insert any number of built-in KPIs in the calculated KPI formulas.

Standard arithmetic operators are supported: addition (+) encoded as %2b, subtraction (-), multiplication (*), division (/) encoded as %2f.

Calculated KPI field names must start with "calculated_kpi_", followed by any valid string, such as, "calculated_kpi_purchaserate".

kpis=installs,loyal_users_rate&calculated_kpi_3days_retention=
retention_day_1%2Bretention_day_2%2Bretention_day_3

kpis=installs&calculated_kpi_rev_per_impression=revenue%2Fimpression

kpis=installs,roi,arpu_ltv,cost,revenue&calculated_kpi_roi_day_7=
(cohort_day_7_total_revenue_per_user-average_ecpi)%2Faverage_ecpi

The following time granularity options are available: Daily.

You use the time frame fields, To and From, to determine the desired granularity in the selected time range. 

Local currency and app-specific time zone are set on the app settings page. Master API data can extract the data using either the system default currency and time zone or using the app-specific time zone and currency. 

The following applies:

• Using the app-specific timezone/currency is supported only If all apps have the same timezone/currency. Otherwise, UTC and USD are used. Time zone and currency are separate. Meaning that if the currency of all apps is the same but the time zones not, then you can use the app-specific currency but not the app-specific time zone. 
• If the preferred time zone was changed in the dashboard within the requested time range, the generated report contains values starting from the most recent time zone change.

Use the following parameters to select the app-specific setting. Note: If you don't use the preferred parameters, you get the default settings, which are USD for currency and UTC for time zone. 

For results to appear in the Master API according to Time Zone, the timezone=preferred parameter must be used.

• Cost data:
  • Availability of different cost dimensions meaning adset, ad, geo, channel, and site ID is ad network dependant. 
  • To get eCPI: If the cost data is available, include both installs and cost in the call. 
  • In general, all sources, including owned media, which use AppsFlyer links and have the cost parameter on the links, fully support cost data, regardless of the requested dimensions. Self-reporting networks, with their own API, usually support cost data with only some of the available dimensions. For example, Facebook doesn’t support grouping by Geo and Channel in the same call. Grouping by either of them separately is supported.
  • Campaigns that have cost data, but no installs data in the date range, are not available via Master API.
• Groupings: Specific groupings are only available for LTV KPIs, Activity, or Retention KPIs. The API returns N/A when the data for a specific KPI is not available. For example, requesting retention_rate_day_7 grouped by af_channel return N/A.
• Maximum rows per report: 200K
• Event names: Master API currently doesn't support event names having the forward-slash / . To overcome this limitation, avoid the user of / in event names. 
• Processing time: selecting more than one app increases the processing time and the response may take longer.
