Where this goes
Place the form inside the body of your page. After a successful POST, the browser follows a 303 redirect to your thank-you page.
Create a form in the dashboard and replace YOUR_FORM_ID with your endpoint ID. No account key belongs in this code.
<form action="https://formdrop.wouldairecommend.workers.dev/f/YOUR_FORM_ID" method="POST">
<label for="email">Email</label>
<input id="email" type="email" name="email" required>
<label for="message">Message</label>
<textarea id="message" name="message" required></textarea>
<input name="_gotcha" tabindex="-1" autocomplete="off" hidden>
<button type="submit">Send message</button>
</form>The detail that matters
Give every field a name; id alone is only for labels and scripts.
After you publish
Send a test from the published page, then check Inbox and Spam. Native forms follow a redirect; fetch clients must request JSON and show errors. Set your allowed domains to the hostnames you actually publish, including any preview hostname you need.
Read the endpoint reference for reserved fields, CORS and redirect rules. Start from the accessible contact template if you need styling.
