Heap’s power comes from automatically capturing a wealth of user interactions in your app, which are classified as events and properties. This autocaptured data is organized into the hierarchy account > user > sessions > pageviews > events, where users belong to accounts, users have many sessions, sessions include pageviews, and during those pageviews, events occur.
Out-of-the-box, Heap provides a wealth of autocaptured events and properties to help you quickly get started with analysis. Reference the platform-specific sections below for the full list of all of the autocaptured data available when you install Heap.
How does Heap define a session?
A session is a period of activity from a single user in your app or website. It can include many pageviews or events. On web, a session ends after 30 minutes of pageview inactivity from the user. On mobile, a session ends after 5 minutes of inactivity, regardless of whether the app’s background or foreground state.
Note that the default events and properties aren’t modifiable. To add a new label for a default event or property, make a copy of it, add a label, then save it as a new event or property.
For information on what session replay captures, see What does session replay capture?
All Platforms
Events
An event is an interaction that a user has with your website or app. By default, Heap autocaptures the following types of events:
View page: A pageview (MDN reference)Click on: A click on an element (MDN reference)Change on: A change in aninput,textarea, orselectelement (MDN Reference)Submit on: A form submission (MDN Reference)Start Session: A session
When you first install Heap, your events page won’t have any labels listed. However, the following two events can be accessed via the analysis chart drop-downs (listed in the ‘Where it appears’ column) to get you started with analysis right away.
| Event | Definition | Where it appears |
|---|---|---|
| Session | A session by a user. | In the Usage over time, Users, Retention, and Influence analysis data drop-downs. |
| Pageview | A pageview by a user. | In all of the analysis data drop-downs. |
Because of the way Heap’s data hierarchy works, all session-level properties are also passed down to these events. This means that, when conducting analysis on an event, you can modify the chart based on any session-level property, such as analyzing the session event and grouping the results by the platform session property.
User Properties
A user is exactly what it sounds like – a unique visitor to your site or app. On the web, a user maps directly to a unique client-side cookie. On iOS and Android, user state is stored in a local database (NSUserDefaults or SQL.) If identified, a user maps to a unique identity.
User properties are bits of data associated with users. Heap provides the following user properties out-of-the-box for all platforms:
| Property | Definition |
|---|---|
| User ID | A randomly generated user ID that’s used to identify a user in Heap. |
| Initial Continent | The continent that the user was identified as being in during the first session. |
| Date First Seen | The timestamp of when the user was first seen by Heap. |
| Initial Location | The initial city, region, and country the user was identified as being in during the very first session. |
| Initial City | The user’s city as determined by their IP address during their very first session. |
| Initial Country | The user’s country as determined by their IP address during their very first session. |
| Initial Region | The user’s region as determined by IP address during their very first session. |
The following three properties are only available if you configure our APIs to capture an identity for your users.
| Property | Definition |
|---|---|
| The user’s email address. If you are capturing this info via the addUserProperties API, this is where it will appear. | |
| Handle | The user’s handle (also known as a username). If you are capturing this info via the addUserProperties API, this is where it will appear. |
| Identity | If you configure your Heap implementation to use the Identify API, this is where the user’s identifier will appear. |
Session Properties
What is a session?
A session in Heap is a period of activity from a single user in your app or website. It can include many pageviews or events. On web, a session ends after 30 minutes of pageview inactivity from the user. On mobile, a session ends after 5 minutes of inactivity, regardless of whether the app’s background or foreground state.
Session properties are bits of data associated with a session. Some notes about session properties:
- While you can create new event properties and user properties, you can’t create new session properties.
- Because of the way Heap’s data hierarchy works, all session-level properties are also passed down to events. This means that, when conducting analysis on an event, you can update the chart based on any session-level property, such as analyzing the session event and grouping the results by the platform session property.
Heap provides the following session properties out-of-the-box for all platforms:
| Property | Definition |
|---|---|
| Session ID | A randomly generated ID number. |
| User ID | The ID of the associated user. |
| Time | The timestamp of when the session began. |
| Platform | The user’s operating system. |

| Country | The user’s country, based on their geolocation data. |
| Region | The user’s region, based on their geolocation data. |
| City | The user’s city, based on their geolocation data. |
| IP Address | The IP address for the user’s session that we use to capture their geolocation data. |
| Source | This indicates which Heap snippet or SDK the data was captured by: either Web, iOS, or Android. |
Event Properties
An event is an interaction that a user has with your website or app. Event properties are bits of data associated with events.
