A TamperMonkey-script for Steam Key registrations (particularly useful with Humble Bundle)

readme.MD

Functionality

When activating a product key on the steam website, this TemperMonkey-script automatically clicks the checkbox to accept the "Steam Subscriber Agreement".

If a product key is part of the URL, for instance after clicking "Redeem" on a game code at humblebundle.com, the script will click the Continue-button for you as well.

How to use this

1. Install the TemperMonkey browser extension (Chrome/Edge)
2. Create a new script
3. Copy paste the contents of the file below

script.js

// ==UserScript==
// @name         Steam: Accept Steam Agreement
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        https://store.steampowered.com/account/registerkey*
// @icon         https://www.google.com/s2/favicons?domain=steampowered.com
// @grant        none
// ==/UserScript==

(function() {
    'use strict';
    console.log('TM: loading');

    const interval = setInterval(() => {
        console.log('TM: checking');
        const elem = document.getElementById('accept_ssa');
        if (!elem || elem.checked || (!elem.checked && elem.checked !== false)) {
            return
        }
        elem.checked = true;
        console.log('TM: SSE accepted');
        clearInterval(interval);

        if (/\?key=.+/.test(location.search)) {
            setTimeout(() => {
                if (window.RegisterProductKey) {
                    console.log('TM: register key');
                    window.RegisterProductKey();
                }
            }, 100);
        }
    }, 100);
})();
