Post-Install Event Setup

Feature Summary: This document describes the recommended approach to integrate with the Kochava system to track post-install events. 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.


JSON Property Description Req.
kochava_app_id This is the unique application ID used to represent the app. Yes
app_version A string representation of the application version number. No
kochava_device_id kochava_device_id should be sent as a unique string that is consistent for each instance of the app on a single device. This will allow Kochava to associate data correctly when a device_id is not available. In the case that there will always be a device_id present and installs will always be sent before post-install events, kochava_device_id can be sent as null.
device_ids This can be the IDFA, IMEI, Android ID, MAC address or a custom variant. You must submit at least one identifier within the device_id object, and may submit more than one. Yes
action Action associated to the API event. Yes
origination_ip The IP address of the device on install. Yes
device_ver Send the device_ver as null, example “device_ver”: “”. Yes
device_ua A string representation of the device user agent as provided by the client. Please ensure that this is URL-encoded. This string is useful when campaigns require fingerprint attribution. Yes
usertime The time the event was completed by the user in Epoch format. No
data 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.
