Point a classic HTML contact form at FormsReach with method POST and your api_key - no backend required.

Minimal form

<form action="https://api.formsreach.com/submit" method="POST">
 <input type="hidden" name="api_key" value="YOUR_ACCESS_KEY" />

 <input type="text" name="name" required />
 <input type="email" name="email" required />
 <textarea name="message" required></textarea>

 <button type="submit">Submit Form</button>
</form>

Requirements

• method="POST"
• action = public submit URL
• Hidden api_key
• Every field you care about needs a name attribute

Tips

• Prefer HTTPS on your site so browsers do not warn on submit.
• Use full-page POST for simplest CORS-free behavior on static hosts.
• For in-page success states without reload, use the JavaScript guide or programmatic submit.
