Use our Javascript Widget to quickly and easily add real-time email verification to your ClickFunnels fields.
You will need:
- A ClickFunnels account
- A sales funnel page with an email field. See the ClickFunnels documentation if you’re having trouble building your funnel.
Creating the Javascript Widget
From the NeverBounce dashboard, go to the Apps menu and select Javascript Widget.
Enter a name to easily identify your application and Save the widget. You can also apply Javascript Widget Settings to protect your account from unauthorized or malicious use.
Once the Widget has been created, you will be provided with an HTML snippet and API key. Keep it safe! You can reset the API Key at anytime from this page.
Inserting the Javascript Widget into ClickFunnels
From the page edit screen, click Elements -> Add Element.
Click Custom JS/HTML Element and drag it to your funnel page. The position doesn’t matter –we will hide this element in a moment.
Click the custom element to open the editor. Ensure the Custom Code Type field is set to 3rd Party Embed Code. Then, click Open Code Editor.
In the Code Editor, copy the HTML snippet from NeverBounce. Close the Code Editor window to return to your funnel page.
Now, click Hide Element to make the JS element invisible. Now your NeverBounce widget can work its magic on your page. You can access hidden elements and edit them or make them visible by clicking Elements -> Manage Elements.
NOTE: The Javascript widget will only validate emails on the preview or live version of the ClickFunnels page, not from the editor screen.
You can check your widget usage for ClickFunnels from the Apps -> Javascript Widget -> ClickFunnels page. To learn more about Javascript Widget functions and settings, check out our Getting Started and Advanced Widget Configuration guide.
Javascript Widget Security Settings
NeverBounce uses a credit system for email verification – this means there is a possibility that people could use your credits if they have access to your Javascript Widget.
NeverBounce provides several settings to eliminate unauthorized use and protect your account.
Add Authorized Domains
Authorized domains and IP addresses prevent your public API key from being used from unauthorized sources. Requests made with your public API key are only accepted when they come from one of your authorized sources.
If you do not specify any authorized domains or IP addresses, all requests made with your key will be processed regardless of location. We recommend adding a list of authorized domains or IP addresses to prevent unauthorized sources using the application and to protect your credit balance.
Throttle Usage
Specifying throttling rules allows you to prevent users from abusing your forms. You can specify multiple rules to limit the number of verifications made in a given timeframe by IP, or even globally across all IP addresses. When the limit is hit, the widget will treat the request as an unknown.
Not specifying throttling rules leaves your widgets at risk for abuse. This may cause your credit balance to deplete or possibly risk account closure.
