You can add a Payment form (or any type of form!) to your Webflow site with just a copy/paste effort.
MightyForm is pretty straightforward and easy-to-use, you can also use a ready-to-go template to create a form.
Make sure you have an active Stripe account that you can connect with the form.
Then, just publish the form and copy the embed code.
That’s the code you use to paste on a Custom Embed Element.
