Cohort analytics API

Use filter parameters to get the necessary data. 

Use groupings to include additional columns and make your reports less granular.

• The table lists the KPIs available and their associated functions. When you call a KPI, all its functions return.
• The following KPIs always return: users, ecpi, and cost 
• Select one additional KPI per call.

KPI format parameters set the format of the KPIs returned. 

This example contains a complete API call.

The name allocated to a CSV file that returns is generated from the API query. The structure is as detailed in the table that follows.

Example CSV file name

cohort_aggregation_type_per_user_kpi_report_app_id_from_to_timezone_currency_hash.csv

Period refers to the day post-attribution, where period 0 is the attribution day. For example, a user installs the app on January 1. This is the attribution day. A purchase made on period 0 means it was made on January 1. A purchase made on period 3 means it was made on January 4. Similarly, a user who installs on January 11, this is period 0. A purchase made on January 14 would be period 3.

If your report date range is January 1 to January 11 users who attributed (installed) during this period are included in the report. No other data is included. 

• The value of the period can be one or more of the following 0-90 and 180. For example, 0, 1, 2, 30, 180. 
• if no period specified, the default values are: 0, 1, 2, and so on to 30, 60, 90, and 180.

The figures that follow map the Cohort analytics user interface to the API parameters. The two solutions - API and user interface are similar but not identical. 

The API version has the following additional options:

• Currency selection
• Timezone selection
• Filtering by period
