steam wishlist script

a simple JavaScript snippet to add Steam games to your Wishlist using the official Steam Store API.

(even those that can't be added, for example - steam news)

overview

This script sends a POST request to Steam’s wishlist API, mimicking the exact behavior of the “Add to Wishlist” button.
It requires that you are logged into Steam in the same browser session.

usage

1. log into Steam in your browser.

2. open Developer Tools → Console (F12 or Ctrl+Shift+I).

3. paste the script with the desired appid.

4. the game will be added to your wishlist.

ethics

• this script does not exploit or bypass Steam systems.

• the same behavior can be replicated via the browser’s dev tools — this just saves time.

• you are fully responsible for how you use it.
