JS Widget can easily integrate to your Instapage forms and validate your emails prior submitting the forms.
What do you need before starting?
Here is the step by step guide how to integrate DeBounce into your Instapage forms.
Navigate to https://app.debounce.io/api and create an API key. Then copy the the public API key.
Then, you need to add your domain URL into approved domains list. This is a security factor which enables the widget only on your domain. Click on "CORS Domains" and add your website address. Please note that the CORS URL must follow these rules: 1) It is not sensitive to http and https 2) It is sensitive to www and non www 3) If your webpage is on a subdomain, you must add subdomain too 4) Enter the root URL of your webpage. Some approved examples: example.com, my.example.com, www.example.com.
Add your public API key into the following code. Now, the integration code is ready. You only need to add it to your Instapage page.
DeBounce_APIKEY = 'YOUR_PUBLIC_API_KEY_HERE';
DeBounce_BlockFreeEmails = 'false'; //Set this value true to block free emails like Gmail.
