// Get the session ID from cookies
var sessionID = document.cookie.match(/sessionid=([^;]+)/)[1];

// Function to add games to the wishlist
async function addToWishlist(gameIDs) {
    for (let i = 0; i < gameIDs.length; i++) {
        let appID = gameIDs[i];

Add Games to Steam Wishlist Script

Description

This JavaScript code allows users to automatically add multiple games to their Steam wishlist by using their game IDs. The script fetches the user's session ID from cookies and makes POST requests to Steam's wishlist API for each game ID provided.

Usage Instructions

1. Prepare Your Game IDs:

   • Identify the Steam game IDs you want to add to your wishlist
   • Use only numbers, separated by commas
   • Example IDs in the code are: 1549970, 440, 730

2. Steps:

   1. Go to Steam's store page in your web browser
   2. Log in to your Steam account
   3. Open Developer Tools:
      • Press F12 or
      • Press Ctrl + Shift + I and click on the "Console" tab
   4. Copy and paste the code into the console and press Enter

Important Notes

• The script includes error handling for failed requests
• It uses async/await for proper request handling
• It includes a rate limiting mechanism to prevent overwhelming Steam's servers
• Replace the example game IDs with your desired game IDs
