<p>Due to security/privacy concerns, JSON REST API (WP API) only allows post meta data (custom field value) for authenticated users.<br />
This plugin is an easy way to make post meta available when unauthenticated.</p>
<p>After activate the plugin, go to WP API Customizer option page.<br />
Click the plus icon to add rows.<br />
Set JSON attributes and custom field names in your posts that you want to use when unauthenticated.<br />
The JSON REST API will provide the data as “post_meta” like the following:</p>
<pre><code>"post_meta":{"your_attribute_a":"Custom Field A value","your_attribute_b":"Custom Field B value"}
</code></pre>


WP API Customizer

Make post meta data (custom field values) available for JSON REST API (WP API) when unauthenticated.

<p>This is an add-on for the <a href="https://wordpress.org/extend/plugins/advanced-custom-fields/" rel="ugc">Advanced Custom Fields</a><br />
WordPress plugin and will not provide any functionality to WordPress unless Advanced Custom Fields is installed<br />
and activated.</p>
<p>The taxonomy field provides a select, multi-select or checkboxes of taxonomy terms (categories, tags, custom taxonomies…)<br />
and the ability to map the selected terms to the post. The post type must support the taxonomy for the mapping to work.<br />
The taxonomy field currently does not provide the ability to add new terms to a taxonomy. The return type of the <code>get_value()</code><br />
api can be changed in the field settings.</p>
