About 42flows SEO Meta
From the official readme · v1.2.1Description
42flows SEO Meta enables REST API write access to SEO meta fields for posts and pages. It auto-detects your active SEO plugin (Yoast SEO, Rank Math, or All in One SEO) and registers only the relevant meta fields with show_in_rest.
This plugin is required if you use 42flows to publish SEO-optimized content to your WordPress site. Without it, SEO titles, meta descriptions, and focus keyphrases cannot be set via the REST API.
Supported SEO plugins
- Yoast SEO —
_yoast_wpseo_title,_yoast_wpseo_metadesc,_yoast_wpseo_focuskw - Rank Math —
rank_math_title,rank_math_description,rank_math_focus_keyword - All in One SEO —
_aioseo_title,_aioseo_description,_aioseo_keywords
What it does
- Detects which SEO plugin is active on your site
- Registers that plugin’s meta fields with
show_in_rest => truefor posts and pages - Adds
sanitize_callback(sanitize_text_field) andauth_callback(requires edit_posts capability) - Does nothing if no supported SEO plugin is detected
What it does NOT do
- Does not modify your existing SEO data
- Does not add any admin pages, settings, or UI
- Does not load any JavaScript or CSS
- Does not store any data
Companion plugin installation and upgrades
When your site is connected to 42flows, 42flows may request that this plugin install, activate, or upgrade a companion plugin (42flows-content) that enables render-time features for posts delivered by the 42flows pipeline (schema markup, attribution footer, page-optimizer REST surface). The companion plugin is downloaded from https://42flows.com/plugins/42flows-content-latest.zip via the /wp-json/42flows/v1/install-companion REST route.
The route requires the requesting user to hold:
install_pluginsandactivate_pluginsfor fresh installs (typically Administrator role)delete_pluginsadditionally when amin_versionparameter is supplied that exceeds the currently-installed companion version, because the upgrade path deletes the existing companion folder before reinstalling
The companion zip URL is hard-coded in the plugin source — it is never user-supplied — so the route presents no SSRF surface. No installation, upgrade, or deletion occurs unless your site is connected to 42flows and the request is authenticated by an administrator-capability user.
Installation
- Install the plugin from the WordPress plugin directory, or upload the ZIP file via Plugins > Add New > Upload Plugin.
- Activate the plugin.
- No configuration needed — the plugin auto-detects your SEO plugin.
Frequently asked questions
Do I need this plugin?
Only if you use 42flows to publish content to your WordPress site and want SEO meta fields (title, description, focus keyphrase) set automatically via the REST API.
What if I don’t have an SEO plugin?
The plugin does nothing if no supported SEO plugin (Yoast, Rank Math, or AIOSEO) is detected. It is safe to keep installed.
Is it safe?
Yes. It only registers existing meta fields for REST API access with proper sanitization and authentication. Only users with the edit_posts capability can write to these fields. All input is sanitized with sanitize_text_field. The companion-install REST route requires install_plugins + activate_plugins capabilities, and additionally delete_plugins for in-place upgrades. The companion plugin source URL is hard-coded — never accepted from request input — so there is no SSRF surface. The optional min_version parameter is validated against a strict X.Y.Z regex before being passed to PHP’s…
Does it work with custom post types?
Currently it registers meta fields for posts and pages. Support for custom post types can be added in a future version.
Changelog
1.2.1
- Auto-enable WordPress plugin auto-updates for 42flows plugins. On every successful
/install-companioncall, both42flows-seo-metaand42flows-contentare added to WordPress’sauto_update_pluginssite option so future feature/security/fix releases reach the customer site without a manual click. Idempotent — safe to call repeatedly. Customers retain control: the WP admin Plugins page still shows a “Disable auto-updates” link. - Why: customers connect their site to 42flows specifically so 42flows manages the meta + render layer; asking them to also manually toggle plugin auto-updates per plugin is onboarding friction with no upside (every WP-side plugin update of these two plugins comes from us anyway).
1.2.0
- Add optional
min_versionparameter to/wp-json/42flows/v1/install-companion. When supplied (semverX.Y.Z), the route compares the installed companion version againstmin_versionand performs an in-place upgrade (deactivate → delete → reinstall → activate) if the installed version is older. Required because WordPress’sPlugin_Upgrader::installrefuses to overwrite an existing plugin folder. Without this parameter, behavior is unchanged: idempotent ensure-installed-and-active. - Upgrade path additionally requires the authenticated user to hold the
delete_pluginscapability, in line with the principle of least privilege. min_versionis validated as^\d+\.\d+\.\d+$before reachingversion_compare()to reject arbitrary input.- Code refactored: install logic deduplicated into a shared helper used by both fresh-install and upgrade paths.
1.1.0
- Add REST route
/wp-json/42flows/v1/install-companionfor authenticated companion-plugin installation (requiresinstall_pluginscapability). Used only when the site is connected to 42flows.
1.0.0
- Initial release.
- Support for Yoast SEO, Rank Math, and All in One SEO.
- Meta fields registered for posts and pages.
