This page runs the real SDK against your App ID and tells you which events reached us. Nothing is faked, which is exactly why passing here means your integration works.
Find it under Settings → API Keys on your game. Never paste your App Secret into a browser, including this one.
When you start the test, the login widget appears in the top-right corner of this page, the same one your players see. Signing in there signs you in to your game's App ID, and the checks watch that happen.
The session opened here is a real session and counts toward that game's analytics. It ends when you leave this page.
