Hooks for WordPress-Only Sites​

After Registration​

add_action('onetap_user_registered', function($user_id, $google_data) {
    // WordPress-specific actions

    // Set user locale
    update_user_meta($user_id, 'locale', $google_data['locale']);

    // Add to newsletter (if applicable)
    // Send welcome email
    // Log registration
}, 10, 2);

Before Login​

add_filter('onetap_allow_login', function($allow, $google_data) {
    // Custom login restrictions
    // Check domain, check blacklist, etc.
    return $allow;
}, 10, 2);

Custom Redirects​

add_filter('onetap_login_redirect', function($redirect_url, $user) {
    // Redirect based on role
    if (in_array('subscriber', $user->roles)) {
        return home_url('/members/');
    }
    return $redirect_url;
}, 10, 2);

Admin Area Access​

Admin Bar​

Google sign-in users see admin bar:

  • If role allows
  • Navigate to Dashboard

Profile Access​

Users can access:

  • /wp-admin/profile.php
  • View/edit profile
  • Change password (if desired)

Restricting Admin​

If you want to prevent admin access for subscribers:

add_action('admin_init', function() {
    if (!current_user_can('edit_posts') && !wp_doing_ajax()) {
        wp_redirect(home_url());
        exit;
    }
});
