Events

Events capture what users do inside a session — custom events you log from the SDK (e.g. Signup_Completed, purchased) as well as automatic events such as Rage Tap and UI Freeze. The Events endpoints return individual event records and aggregated event analytics.

Note
Looking for how to send events from your app? See the SDK Send Custom Events guide. This page documents how to read events back through the Data Access API.

Endpoints

POST /api/data-access/v1/event

POST /api/data-access/v1/event/analytics

Filtering events

The event list has a focused, fail-closed filter surface — a date window plus the attributes below. Anything else returns 400. Every attribute accepts only equal; event_name also accepts in with a list. Any other operator returns 400.

Attribute	Operator(s)	Value
`event_name`	`equal` / `in`	One name or a list of names
`device_model`, `device_manufacturer`, `os_version`, `app_version`, `country`, `screen_name`	`equal`	A single string
`device_platform`	`equal`	`1` = Android, `2` = iOS, `3` = Web
`has_video`	`equal`	Boolean
`event_custom_property`	`equal`	With `property_name` + value (one property filter)
`date_range`	date operators	See Filter Operators

Sections

An event record groups into four sections. Omitting show_only returns the default set ["eventProperty", "sessionProperty"] (the event's data plus its parent session — including sessionId, the join key) — pass show_only to request more:

Section	Contents
`sessionProperty`	The parent session: `sessionId`, `durationSec`, `totalScreen`, `uniqueScreensCount`, `networkType`, `sessionNumber`, `isCrashed`, `country`.
`userProperty`	The user's id (`uxcamuserid`, `kUXCam_UserIdentity`) plus custom user properties.
`deviceBasics`	`deviceId`, `appVersion`, `osVersion`.
`deviceHardware`	`model`, `manufacturer`, `class`, `platform`. Request `device` to get both device sub-sections.
`eventProperty`	The custom properties attached to this event.

List events

POST /api/data-access/v1/event

Request

Send a JSON body; the API key rides in the X-Api-Key header.

app_id — required; the app to read.
filters — optional; the focused surface above, plus a date_range window (omit for the last 30 days).
show_only — sections to return. Omit for the default ["eventProperty", "sessionProperty"]; the example below requests all four.
page_size — records per page, 1–2000 (default 500).
cursor — opaque cursor for the next page; omit for the first page.

📘
Note
eventDate is when the event happened on the device — the field the date window and sort order use. eventUploadedDate is when the device delivered it to UXCam and can lag eventDate by days.
Event device.platform is the label ("android" / "ios"), consistent with the Sessions and Users endpoints. (The device_platform filter input still uses the numeric codes 1/2/3.) Custom event-property values are returned as strings (e.g. "1499").

Analyze events

POST /api/data-access/v1/event/analytics

Returns event counts, optionally grouped by the dimension(s) you pass in group_by. Omit group_by for an ungrouped total across all events (the example below groups by event_name). Event analytics are count-based (no averages). Filter attribute names differ on /event/analytics: use device_country (not country), event_screen_name (not screen_name) and session_has_video (not has_video). event_custom_property is not accepted on /event/analytics.

Default metrics

Metric	Description
`event_count`	Total events
`event_unique_user_count`	Unique users who triggered the event
`event_unique_session_count`	Unique sessions containing the event

Group-by dimensions

Pass in group_by (up to two):

Event — event_name, event_screen_name
Device — device_model, device_manufacturer, device_class, device_os_name, device_os_version, device_type, device_platform
App — app_version
Browser (web) — browser_name, browser_version
Time bucket — event_recorded_month, event_recorded_week, event_recordedon_day
