The plugin stores its configuration in individual WordPress options, all prefixed rcfwc_. This reference lists them for developers scripting deployments, writing migrations, or debugging a site’s state directly in the database.

Checkbox options store an empty string when unticked, so test them for truthiness rather than comparing to a specific value.

API keys and appearance

• rcfwc_key — the reCAPTCHA v2 site key.
• rcfwc_secret — the reCAPTCHA v2 secret key.
• rcfwc_theme — light or dark.
• rcfwc_tested — yes once the Test API Response check has passed. Reset to no whenever either key changes.

Keys can also be supplied as constants in wp-config.php, which take precedence over the stored options:

define('RECAPTCHA_WOO_SITE_KEY', 'YOUR_SITE_KEY');
define('RECAPTCHA_WOO_SECRET_KEY', 'YOUR_SECRET_KEY');
