Quick Start


  1. Helika API Key
    1. You’ll need a Helika API Key in order to instantiate the plugin.
    2. Please reach out to your Client Success Manager in order to receive an API key for your organization.
  2. Event Taxonomy
    1. We strongly recommend following our suggested Event Taxonomy for game event handling and structure. This is due to how we ingest and store data from your game, in order to make it accessible through our Game Management Platform.

API Reference

Game Event Taxonomy

Automatic Data Capture

The Helika SDK automatically appends selected data fields in the event along side your customized data event.

game_idstringrequiredThe Game ID that we will use to identify your game's events (if set in the event itself, that overrides the default game_id set on initialization
created_atDateTimerequiredThe timestamp when the event was created.
session_idu4requiredThe sdk generates a new Session ID when the Helika Object is created.
player_idstringoptionalYou can set the "player_id" to identify all events generated after will be associated with this specific player.

Demo Project

A demo project has been created to demonstrate how the Helika UE SDK functions. Please use the following repo as a reference:

Helika UE SDK Demo Project


It is recommended that you verify events are being ingested correctly by sending some test events via the SDK. Successfully sent events should have a 200 status response.

Check within your portal for the events to appear in the Data Ingestion Summary.

The Data Ingestion Summary report can be found in the side menu:

  • Data Summary > Data Ingestion Summary

The Data Ingestion Summary will display information such as:

  • Which environment the events are being sent to
  • Total Event Volumes
  • Types, and Sub Types Seen
  • A table for the raw event stream, with raw payload.


Ingestion Delays

Please expect up to the following delays during event processing, before results are populated:

  • Production: 15 minutes
  • Development: 2 hours

After seeing some test events appear, this report can be used to monitor your ongoing events and event volumes, as they are added.
