Keep your form

Your form stays on your site with your styling. Mountly handles the backend.

One submit URL

Use a normal form action or API request without embedding a hosted widget.

Public docs first

Read the guides and API reference before you ever wire a live form.

HTML form submission
HTML
<form action="https://api.mountly.io/submit/<form-id>" method="POST">
  <input type="email" name="email" required />
  <input type="text" name="message" />
  <button type="submit">Send</button>
</form>

Best fit if you

  • You already ship websites with their own design and form UI
  • You build client sites and do not want a new backend each time
  • You want API access without moving to a hosted form builder

How it works

Go live in three steps

Create the form in Mountly, connect your form to the submit URL, and confirm the first submission in your workspace.

  1. 01

    Create the form and copy the submit URL

    Set it up once in Mountly, then reuse that submit URL anywhere you need to collect entries.

  2. 02

    Point your form at the submit URL

    Keep the form on your own website. Update the action, send a POST request, and keep your current styling intact.

  3. 03

    Send a test and watch it land

    Confirm the first entry in your workspace, then add redirects, notifications, or API workflows when you need them.

FAQ

A few common questions

Start here if you want to pressure-test whether Mountly fits the sites you already ship.

Does Mountly host my forms?

No. Your forms stay on your own website. Mountly handles submission intake and the backend rules around it.

What is public in the API?

The docs and live reference cover forms, form entries, authentication, and conventions before signup.

How do access tokens work?

Tokens can be service-wide or scoped to a form, and they support permissions, expiry, and revocation.

What happens after a submission succeeds?

Mountly stores the entry, can trigger email notifications, and can redirect the browser with per-form rules.
