What Are URL Prefill Parameters?
A URL Prefill Parameter is a way to pass information through a URL. You can insert parameters into your URLs to modify content or track information.
What are URL Prefill Parameters used for in On2Air Forms?
Using URL Prefill Parameters with On2Air Forms allows you to automatically add data to a form field.
There is a URL Prefill Key setting in every field option and in the Create Configuration option in On2Air Forms
With this setting, you can set a field’s default value or the entire form’s default values from the URL by adding a Key to the URL Param setting. Then you add a Key and Value to your URL.
Example: www.yourformsurl.com?key=value

How do you format a URL Prefill Parameter? (Example included)
URL prefill parameters are made of a key and a value separated by an equals sign (=). The first parameter always comes after a question mark in a URL.
Key/Value: ?key=value
Full URL Format: www.on2air.com/form/yourformcode?key=value
How to set Default Values for Fields or Entire Forms with URL Prefill Parameters
You can add a URL Prefill Key in the Field settings of On2Air Forms or the Form settings to add a default value to a field.
If we set the URL Prefill key to product in the URL Prefill key field in On2Air, we can add a value of Backups or another value in our URL.
For example, the URL could be www.on2air.com/form/yourformcode?product=Backups where product is the key and Backups is the value.
When you share this URL with someone to complete the form and they click this URL www.on2air.com/form/yourformcode?product=Backups, the form field that has the URL Param key with product will automatically add Backups as the data in your field.
