Automatically stores the meta data from the <code>meta</code> field of a wordpress REST API posts (<a href="https://developer.wordpress.org/rest-api/reference/posts/#create-a-post" rel="nofollow ugc">/wp-json/wp/v2/posts</a>) or pages (<a href="https://developer.wordpress.org/rest-api/reference/pages/#create-a-page" rel="nofollow ugc">/wp-json/wp/v2/pages</a>) POST in the meta data associated with the created page or post using <a href="https://developer.wordpress.org/reference/functions/update_post_meta/" rel="nofollow ugc">update_post_meta</a>. The key / value information sent in the REST POST ‘meta’ object field is stored as both ‘key’ and ‘_key’ to support different plugin formats. 
For example, if trying to set the YOAST SEO Plugin values dynamically when creating a page from the REST API, you would simply add the fields to the meta field of the REST POST data when you POST the endpoint, and the plugin values will be added to the page:
<pre><code>{
...
 'meta': {
 'yoast_wpseo_title': "Title set from REST call"
 'yoast_wpseo_metadesc': "Meta description set from REST call"
 }
...
}
</code></pre>
Use this plugin when dynamically creating pages with the WordPress REST API to support modifying plugin settings for pages/posts created using the REST API!
