What it would submit

2. See what really arrives

Temporarily set your form's action to the echo endpoint, submit it once, and you'll get a page showing every field that arrived, what each control field means, and anything that looks wrong. Nothing is stored or emailed.

<form action="https://formpit.com/tools/echo" method="POST">

Sending with JavaScript? fetch() the same URL with Accept: application/json and you get the result as JSON. The endpoint tester does this for you.
