Is it possible to redeem a steam key code using the below method? I checked robots.txt and couldn't find anything that specfically disallows it but get an ok=false in the response so I'm assuming this isn't allowed. I understand that this is a garbage question but I just wanted to rule this out before I explore other avenues, thanks for taking a look.

const emailBody = form.elements['emailBody'].value;

// Get all Steam keys
const re = /((?![^0-9]{12,}|[^A-z]{12,})([A-z0-9]{4,5}-?[A-z0-9]{4,5}-?[A-z0-9]{4,5}(-?[A-z0-9]{4,5}(-?[A-z0-9]{4,5})?)?))/g;
var steamKeys = emailBody.match(re);

// Submit all Steam keys
steamKeys.forEach(function (item, index) {
    //https://store.steampowered.com/account/registerkey?key=XXXXX-XXXXX-XXXXX
    // Example POST method implementation:
    async function postData(url = '', data = {}) {
      // Default options are marked with *
      const response = await fetch(url, {
        method: 'POST', // *GET, POST, PUT, DELETE, etc.
        mode: 'no-cors', // no-cors, *cors, same-origin
        cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
        credentials: 'same-origin', // include, *same-origin, omit
        headers: {
          'Content-Type': 'application/json'
          // 'Content-Type': 'application/x-www-form-urlencoded',
        },
        redirect: 'follow', // manual, *follow, error
        referrerPolicy: 'no-referrer', // no-referrer, *no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url
        body: JSON.stringify(data) // body data type must match "Content-Type" header
      });
      return response;
    }

    postData('https://store.steampowered.com/account/registerkey?key='+item)
      .then(data => {
        console.log('https://store.steampowered.com/account/registerkey?key='+item,data); // JSON data parsed by `data.json()` call 
    });
});
