Stop form spam with reCAPTCHA

GR

Register your site with Google reCAPTCHA and paste the keys into your form. The site key renders in the published form, the secret stays server-side, and low-scoring submissions are flagged.

What the Google reCAPTCHA integration does

  • Verification happens server-side, so a bot cannot skip it by posting directly.
  • Set a minimum v3 score; verdicts below it are marked suspicious rather than silently dropped.
  • Keys are yours, so reCAPTCHA analytics stay in your Google account.

What it looks like

A server-side verification result stored with the submission's score.

How to connect Google reCAPTCHA to your form

  1. 1

    Register your site at google.com/recaptcha/admin and copy the site and secret keys.

  2. 2

    Paste them below — the site key is used in your published form, the secret stays server-side.

  3. 3

    Send a test event to confirm HelloForms can reach Google's verification endpoint.

What you’ll need

  • reCAPTCHA secret key.
  • Site key — Public key rendered in your form.
  • Minimum score (optional) — v3 only. Verdicts below this show as suspicious in the delivery log. Defaults to 0.5.

Credentials are stored server-side and never rendered in your published form. Every delivery attempt is logged, transient failures are retried with backoff, and repeated failures disable the destination instead of retrying forever.

Who uses it

  • Public contact and quote forms that attract bot traffic.
  • Newsletter signups where fake addresses damage deliverability.
  • High-traffic landing pages where spam drowns real leads.
