View the details of all the outcomes associated with your app.

​
Overview

Use this API to retrieve Outcome metrics associated with your OneSignal app, including push notification interactions and custom-defined events. Outcomes include data points like:
  • Clicks: Number of users who clicked on a push.
  • Confirmed Deliveries: Number of confirmed message deliveries.
  • Session Durations: Number of sessions initiated.
  • Custom Events: Actions like purchases, form submissions, or any event your app tracks via custom Outcome names.
For details on configuring custom Outcomes, refer to the Outcomes documentation.
Outcomes are stored for approximately 30 days. To retain this data, you should regularly export it before it expires.

​
How to use this API

This API allows you to filter and aggregate Outcome data using several query parameters.

​
outcome_names

Specify one or more Outcome names with an aggregation type suffix (.count or .sum). Default Outcome names:
  • os__click.count – Push notification clicks.
  • os__confirmed_delivery.count – Confirmed deliveries.
  • os__session_duration.count – Total sessions.
Custom Outcome names:
  • You can track any custom event name (e.g. Purchase, Signup).
  • If the custom name contains a comma, include only one name per request to avoid parsing issues.
  • Example: outcome_names=os__click.count,Purchase.count

​
outcome_time_range

The time range values can be one of the following:
  • 1h = (default) the last 1 hour data.
  • 1d = the last 1 day data.
  • 1mo = the last 1 month data.

​
outcome_platforms

Maps to the subscription type property. Default is data from all platforms enabled for your OneSignal App.
device_typetype
0iOSPush
1AndroidPush
2FireOSPush
5ChromePush
8FirefoxPush
11Email
14SMS
17SafariPush
Example: outcome_platform=0 for iOS outcome_platform=17,8 for Safari and Firefox.

​
outcome_attribution

The way in which the Outcome occurred:
  • direct = the Outcome occurred when the user interacted with the message. Some Outcomes only have direct attribution like os__click and os__confirmed_delivery because they only occur as the direct result of the message.
  • influenced = the Outcome occurred within the Time Window of the message being sent, but the user never interacted with the message. See Outcomes for details.
  • unattributed = the Outcome occurred without a direct or influenced attribute.
  • total = (default) the sum of direct+influenced+unattributed.
