SDK Initialization

Your game's SDK Initialization tab in the Y8 Developer Portal holds the two credentials the SDK needs, along with a ready-made initialization snippet already filled in with them.

Credential	What it is for
App ID	Identifies your application. Always required.
Game ID	Identifies the game to platform services. Required for advertising; omit it if your game shows no ads.

Copy them exactly as shown.

Prefer the snippet on that tab

It is the same integration described in Getting started, but with your real App ID and Game ID already substituted in, so it runs as it stands. Copying it is less error-prone than transcribing the credentials by hand.

The same tab is where you register development addresses, so that signing in works while testing from a phone, a tunnel, or another machine on your network.

Next Steps

With your App ID and Game ID in hand, continue to Platforms to install the SDK for your engine, then to Getting started to initialize it.
