App Activity

GET /clients/{client_id}/analytics/apps/{app_id}/activity

Returns a daily time-series of activity for a specific application. Supports multiple metrics covering active time, session count, and user count.

This endpoint uses a different data source than user/device activity. App metrics come from the app_usage_reports table (daily aggregated usage per user per app), not from heartbeats.

Use Case​

Use this endpoint to:

  • Display app usage trends on the app detail page (line chart, area chart)
  • Track adoption with daily user counts
  • Monitor engagement depth via active time and session count
  • Compare usage across time periods

Path Parameters​

ParameterTypeDescription
client_idstring (uuid)Unique identifier for the client organization
app_idstring (uuid)Unique identifier for the application

Query Parameters​

ParameterTypeRequiredDescription
granularitystringYesAggregation granularity: daily, weekly, monthly, quarterly
start_datestringYesStart of date range (YYYY-MM-DD)
end_datestringYesEnd of date range, inclusive (YYYY-MM-DD)
metricstringYesMetric to retrieve. See Available Metrics.

Available Metrics​

MetricLabelDescriptionDB Aggregation
active-timeActive TimeTotal active time in milliseconds across all usersSUM(app_usage_reports.total_active_ms) GROUP BY activity_date WHERE application_id = ?
session-countSessionsTotal sessions across all usersSUM(app_usage_reports.total_session_count) GROUP BY activity_date WHERE application_id = ?
user-countDaily UsersDistinct users who used the app per dayCOUNT(DISTINCT app_usage_reports.user_id) GROUP BY activity_date WHERE application_id = ?

Response​

Returns an ActivityTimeSeries.

For active-time, value is in milliseconds. Consumers should format this for display (e.g. convert to hours/minutes).

Error Responses​

400Invalid parameters (bad date format, range exceeds 90 days, unknown metric)
401Authentication required
403Insufficient permissions for this client
404App or client not found
500Server error

Example Error Response​

{
  "error": {
    "code": "invalid_parameter",
    "message": "Unknown metric: interactions. Valid values: active-time, session-count, user-count",
    "details": {
      "metric": "interactions"
    }
  }
}

Notes​

  • The response always includes every date in the range, even weekends or days with zero activity.
  • All dates are in the client's configured timezone.
  • active-time values are in milliseconds. Divide by 3,600,000 for hours.
  • user-count counts distinct users per day, not cumulative.
  • Data source is app_usage_reports, which is partitioned by month. Queries spanning month boundaries read from multiple partitions transparently.
