Form handling is a built-in feature on Netlify. Basic setup doesn't require
any additional JS or API calls. Just add a data-netlify="true"
attribute or netlify
to the tag of your form. Netlify build bots
are parsing your website, while it deploys, to find forms marked with the
attributes.
All form submissions are getting to the Netlify Forms interface of your website.
In your website dashboard, go to the Forms → Active forms.
The tab contains a list for all the forms you have on the website. Each form
is visible in the list named by the value of the form name
attribute.
