Use the direct link, you can load QiotaPay.js directly. Once loaded, qiotapay will be available on your website.
Adding the <script> tag loads Qiota’s JavaScript file.You may include this either within your <head> tag or inside the <body> part of your HTML, before the end of the page.
...
<script src= "https://[beta/www].qiota.com/assets/getQiotaPay.js" ></script>

The <div> qiota tag container                                                        

The getQiotaPay.js file allows you to render a Qiota widget on the client side.
 Configure the container and form where the QiotaPay Widget will add the payment method nonce. Make sure to replace TOKEN CLIENT with your generated client token.


...
<div class= "qiota" >   </div>
...
                                                  

The widget will appear exactly where this <div> tag is included on your page. When the getQiota.js file is loaded, this <div> tag will get populated.
 You should integrate this script before the end body tag.
