Registers SEO meta fields for WordPress REST API write access. Required for 42flows content delivery.

== Description ==

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](https://42flows.com) 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 => true` for posts and pages
* Adds `sanitize_callback` (sanitize_text_field) and `auth_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 make any external API calls
* Does not store any data

== Installation ==

1. Install the plugin from the WordPress plugin directory, or upload the ZIP file via Plugins > Add New > Upload Plugin.
2. Activate the plugin.
3. 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`.

= 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 ==

= 1.0.0 =
* Initial release.
* Support for Yoast SEO, Rank Math, and All in One SEO.
* Meta fields registered for posts and pages.
