How to Setup

Installing DeBounce JavaScript Widget!

DeBounce email validation and checker JavaScript widget is easy to install. Copy the code below and paste just before the </body> tag of your website.

<script type="text/javascript">
DeBounce_APIKEY = 'YOUR_PUBLIC_API_KEY_HERE';
DeBounce_BlockFreeEmails = 'false'; //Set this value true to block free emails like Gmail.
</script>
<script async type="text/javascript" src="https://cdn.debounce.io/widget/DeBounce.js"></script>

Important Notes (read carefully):

  1. You can get your API key from DeBounce dashboard.
  2. Do not forget to add your website address into approved CORS domains of your API key.
  3. For security reasons, use the Public JavaScript API (starting with public_) and avoid using the main API key.
  4. The widget will search for all fields with the attribute type="email" and name="email" and any other attribute which contains the word email.
  5. Generally, it is suggested to send transactional emails to Valid, Accept-all and Unknown emails. So, this widget will consider these three categories as valid.
