Before You Start

Here are some things to know before you begin:

• This guide assumes you’re already familiar with the Custom HTML integration option in the campaign builder.
• The name and value attributes are always required for hidden fields.
• Hidden input fields are identifiable by the type attribute, and do not appear visible to your visitors but allow you to pass additional details with your form.
  For example:

    <input type="hidden" name="Language" value="English">

Add Hidden Fields

The following is an example of a simple HTML form including two input fields to collect the name and email address and a hidden input field that specifies the language.

<form src="http://www.example.com/form.php" method="post">

    <input type="text" name="name" placeholder="Name" />

    <input type="email" name="email" placeholder="Email Address" />

    <input type="hidden" name="Language" value="English">

    <input type="submit" name="submit" value="Submit" />
