Why isn't my reCAPTCHA showing up on my form?

Cause one: the element was never added

Only the Contact us page template comes with reCAPTCHA already in place. Every other registration form needs the element added by hand: open the page editor, find reCAPTCHA in the panel on the left, and drag it onto the page.

systeme.io recommends placing it right after the form's input fields and before the submit button.

Before any of it works: keys from Google

A reCAPTCHA also needs two keys generated outside systeme.io, at Google's reCAPTCHA site. Registering a site there asks for a label, the reCAPTCHA type, which systeme.io's own walkthroughs set to Challenge (v2) with the "I'm not a robot" checkbox, and the domain the form will run on.

Google then issues a Site key and a Secret key. Those get pasted into systeme.io, not into the page itself: your profile picture, then Settings, then Custom domains, the three dots next to the domain, then Settings, then the reCAPTCHA Settings section, then Save.

The keys sit on the domain, not on the page or the funnel step. Every page using that domain shares the same pair.

Cause two: two domains that do not match

systeme.io states this condition twice, once for each version of the setup: the domain name connected to the funnel, or selected for the funnel step, has to match the domain that was registered in the Google reCAPTCHA console when the keys were generated.

A form running on a domain that was never registered with those specific keys is the second documented reason the widget fails, even when the element is sitting on the page and the keys are saved.

A different failure: an error instead of nothing

A visible message reading "reCAPTCHA verification error, please try again" is a separate, later problem. systeme.io attributes it to the free quota for reCAPTCHA Enterprise being used up, fixed by adding an active billing account in the Google reCAPTCHA console. That is not the same fault as the widget never appearing at all.
