<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><strong>ACF PRO 5.0+ is no longer supported, ACF PRO <a href="https://www.advancedcustomfields.com/resources/date-time-picker/" rel="nofollow ugc">has its own date and time picker</a></strong></p>
