Tips

Use HTTPS pages for iframes. For production, allowlist your domain in the console and set enforce_domain=T on the key. Local file:// tests often send no Referer — add &domain=localhost to the iframe URL and allowlist localhost in the console. HMAC t/token expire in 15 seconds: regenerate immediately before opening the page.
