Post-Install Event Setup

This document describes the recommended approach to send install and event tracking information to Kochava. It is important to follow these API instructions in order to avoid data corruption and maximize the effectiveness of Kochava in your environment.


NOTE: For examples of post-install events, refer to our Post-Install Event Examples support documentation.

Install and Startup Tracking

To track the installation and startup of your application, please refer to the Server-to-Server Install Notification Integration Guide. Once Kochava has registered an install for a device, features can be tracked via server-to-server API according to the specifications provided here.

Post-Install Event API

To send a usage event from your application, call the following endpoint with a POST payload containing the desired JSON elements.

data event_name: event string
event_data: value string
Each event is a JSON object – see examples.

event_name -> A string representation of an event that has happened.

event_data -> A corresponding value associated to the event_name. event_data is not required but useful for monetary tracking for correlated events (e.g. event_name -> “Level DLC Purchased” and event_value -> “20”).


BEST PRACTICES: Send the event data as a JSON object per the example below.

BEST PRACTICES: Sending single level JSON objects is the required method. DO NOT send nested JSON as it will not render correctly in the analytics system.
