Configuring server-side submission to reduce bot form submissions

We recently started using Pardot Form Handlers to capture prospects from Webflow form submissions from our Webflow forms, hosted on our website. These are created by pasting HTML snippets from Pardot into Webflow Forms.

Because this voided Webflow’s built-in reCAPTCHA (see this post for more), we’ve been receiving a high volume bot submissions.

We’ve taken steps to try to mitigate, but the only thing left to do, it seems, is to configure server-side submission (#2 on the article below).

Has anyone found a better workaround for this or have experience in configuring server-side submissions?
