You can use our client-side APIs to:

• Bring in additional data that Heap does not autocapture, including custom events and properties
• Manage user identity across browsers, sessions, and in situations where multiple users are accessing the same device
• Capture mobile events via the iOS/Android Event Visualizer

We have server-side equivalents of several of our client-side APIs, such as track and addUserProperties. If you’re unsure whether to bring in this data via the client or server-side, see Tracking Web Custom Events Client-side vs. Server-side.

Prerequisites

Before using our client-side APIs, you’ll need to have installed Heap on your website or app. For installation instructions for web, mobile, react native, and third-party platforms, jump to our developer guides.

Note that select APIs have their own individual prerequisites, as listed in each API section below.
