Create a formCopy Anchor Link

Choose Create a form, give it a name and pick a starting point:

• Contact form, Waitlist signup, Feedback survey or Event RSVP start with ready-made fields and a matching design.
• Blank form opens the form builder so you can add your own fields.
• Endpoint only skips the builder. Pick it when you already have a form on your site.

Each option is described in Create a form.

Put the form on your siteCopy Anchor Link

Open the form's Setup tab and answer How do you build your site?

• Site builder: copy the embed code and paste it into Webflow, Framer, WordPress, Squarespace or Wix. See Site builders.
• Code: copy a snippet for HTML, React, Next.js, Vue, Svelte or Astro. Your design gives you the styled form from the builder, and Your own styles gives you plain markup that picks up your site's CSS.
• AI tool: copy a prompt for Claude Code, Cursor, v0 or a similar tool. See Use an AI coding agent.

If you write the form yourself, use the endpoint from the Setup tab as the form's action and give every input a name:

<form action="https://api.nisuform.com/s/YOUR_FORM_KEY" method="POST">
  <label>
    Name
    <input type="text" name="name" required>
  </label>
  <label>
    Email
    <input type="email" name="email" required>
  </label>
  <label>
    Message
    <textarea name="message" rows="5" required></textarea>
  </label>
  <input type="text" name="_gotcha" tabindex="-1" autocomplete="off" style="display:none">
  <button type="submit">Send</button>
</form>

The hidden _gotcha input is a honeypot that catches bots. Keep it hidden and empty. See Special fields.

Send a testCopy Anchor Link

Choose Send a test on the Setup tab. It stores a sample submission marked as a test and fires your notifications, without counting toward your monthly limit.

Then send a real one from your site. The Setup tab watches for it and shows Your form is live as soon as it arrives. You can also test from a terminal:

curl https://api.nisuform.com/s/YOUR_FORM_KEY \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d '{"name":"Jane Doe","email":"jane@example.com","message":"Hello!"}'

A successful request answers {"ok":true,"submissionId":"..."}. Submissions from your site and from cURL are real, so they count toward your monthly limit.
