Netlify Forms

Mark a form for detection with data-netlify="true" (or the bare netlify attribute — equivalent) on the <form> tag. Forms are detected by parsing the final built HTML at deploy time — there is no runtime API call or backend code. Client-side/JS-rendered/SSR forms are NOT in the built HTML and are never detected on their own; they require a static skeleton file (see below).

Prerequisite: form detection must be enabled once in the Netlify UI (Forms > Enable form detection). Takes effect on the next deploy.

Static HTML form

<form name="contact" method="POST" data-netlify="true">
  <p><label>Your Name: <input type="text" name="name" /></label></p>
  <p><label>Your Email: <input type="email" name="email" /></label></p>
  <p><label>Message: <textarea name="message"></textarea></label></p>
  <p><button type="submit">Send</button></p>
</form>
