Finding your Match sharing code
To get data for all your recent matches, launch CS2, go to the Watch tab, and select Your Matches. Then take your oldest available match and click the "Copy match sharing code" button in the bottom right.
There's no need to provide a sharing code for each match manually. Once you've provided the first valid sharing code, Leetify will fetch all subsequent matches automatically.
