Why use Form2Lead with HTML5?

Plain HTML pages cannot process server-side POST requests on their own. Form2Lead gives you a working form backend in 30 seconds: set the form action to your endpoint, add a `_gotcha` honeypot field, and every submission is validated, spam-checked, emailed, and stored — with zero JavaScript.

Prerequisites

✔Static HTML webpage
✔Form2Lead endpoint URL

Step-by-Step Integration Guide

01. Set Form Action

Set your form element action attribute to your Form2Lead URL.

<form action="https://form2lead.com/api/v1/f/YOUR_FORM_ID" method="POST">
  <input type="text" name="name" placeholder="Full Name" required />
  <input type="email" name="email" placeholder="Email Address" required />
  <textarea name="message" placeholder="How can we help?" required></textarea>
  <button type="submit">Send</button>
</form>

02. Add the Invisible Honeypot Field

Add a hidden `_gotcha` input so Form2Lead silently drops automated bot submissions.

<input type="text" name="_gotcha" style="display:none !important" tabindex="-1" autocomplete="off" />

03. Lock Down Allowed Domains

In your Form2Lead form settings, add your site origin (for example `example.com`) to Allowed Domains so only your pages can post to the endpoint.

Does plain HTML form submit require JavaScript?

No. Standard browser POST submission works out of the box without a single line of JavaScript.
