How to effectively create and use hidden fields in your registration page url.

Updated over a week ago

*** IMPORTANT - Hidden and custom fields are only available in PRO and ENTERPRISE versions of EasyWebinar. 

Hidden fields are great for capturing the lead origin from your webinar registrants. 

NOTE:  UTM parameters pass through to Google analytics WITHOUT the use of hidden fields.

What is a hidden field and how is it different from a custom field that is text, number or select box?

A hidden field is a field passed to the registration page from an outside source such as information from the page or link before it. 

The most popular of which would be a lead source or UTM parameter from a Facebook ad or a webpage click. 

A hidden field comes to EasyWebinar in the form of a URL Parameter. 


Everything from the "?" on define the hidden field. 

When adding hidden field parameters always start with a question mark "?". Additional parameters are connected with an ampersand "&".

Why use a hidden field? 

Hidden fields are great for lead sources to be sent to your CRM or to show up in your EasyWebinar csv report. 

At a source level all hidden fields show up in your EasyWebinar csv report. 

At a secondary level all hidden fields are sent to your CRM. Your hidden field MUST BE correctly tied to a custom field in your CRM inside of EasyWebinar's Integration tab. 

If you want to see where your leads are coming from to your webinar I would recommend first and foremost to use UTM parameters. Not only are they perfectly designed for this, but they get passed to Google Analytics reports as well. 

If you are not concerned with using Google's UTM formats then any value will work as long as you understand it's meaning to you and your company. 


So, it would be ad-source=facebook, ad-source=google, ad-source=blogpost

and you would add it to your registration link as such:

With hidden fields if you are not concerned with UTM parameter protocols then the wording does not matter. only the format does. 

always start with a "?"
additional hidden fields are added with a "&" such as:

The above example would give you data to know that your registration came from your blog post, clicking on the sidebar banner with the image of the sunset. Assuming you have different options and you need to know all of that. In many cases this is can be very helpful. 

The benefit of a hidden field comes in passing this data to your CRM to be able to create the appropriate reports so you know your advertising and marketing efforts are paying off or need adjusted.
