If you wish to ‘Create comments’ using REST API, without exposing Administrator credentials to the Front-End application, you are at the right place. Since WordPress 4.7, REST API was natively included in WordPress.
In order to ‘Create a comment’ , the authentication for a user with ‘Administrator’ role is required. While this is a deliberately done for security reasons, such implementation makes it very hard for Front-End applications to implement a simple ‘Post Comment’ or ‘Reply Comment’ function.
This plugin fulfils such requirement by extending the existing WordPress REST API endpoints.
Requirements:
Minimum PHP version: 7.0 
Minimum WordPress version: 5.5
Installation:
Download the plugin form wordpress marketplace install it like any other WordPress plugin. 
After the installation activate the plugin through the ‘Plugins’ menu in WordPress
Endpoint:
When this plugin is installed one new endpoint is added to the wp/v2 namespace.
 Endpoint 
 HTTP Verb 
 Permalinks
 */wp-json/wp/v2/comments/create 
 POST 
 enabled
 */?rest_route=/wp/v2/comments/create 
 POST 
 disabled
Usage:
<ol>
<li>Create a Comment</li>
</ol>
To create a comment using REST API, send a <code>POST</code> request to:
<blockquote>
<code>/wp-json/wp/v2/comments/create</code> – if permalinks is enabled on your wordpress website.
</blockquote>
Or
<blockquote>
<code>/?rest_route=/wp/v2/comments/create</code> if permalinks is not enabled on your wordpress website.
</blockquote>
With a JSON body, as shown bellow:
<pre><code>`Json
</code></pre>
{ 
 “post”: “Post ID”, 
 “author_name”: “Comment Author’s name”, 
 “author_email”: “Comment Author’s email”, 
 “content”: “Comment content” 
} 
 `
The content may also be send as an object:
<pre><code>`Json
</code></pre>
{ 
 “post”: “Post ID”, 
 “author_name”: “Comment Author’s name”, 
 “author_email”: “Comment Author’s email”, 
 “content”: { 
 “raw”:”Comment content” 
 } 
} 
 `
Set header to:
<pre><code>`
</code></pre>
content-type: application/json 
 ` 
If successful, you should receive a response with the data of the created comment:
<pre><code>`Json
</code></pre>
{ 
 “id”: “[comment id]”, 
 “status”: “[comment status]”, 
 “message”:”[server response message]” 
} 
 `
In response header the status code should be:
<pre><code>`Http
</code></pre>
HTTP 201 Created 
 `
<ol>
<li>Reply a comment</li>
</ol>
To reply a comment you just need to add the field parent for the parent comment to the JSON body
<pre><code>`Json
</code></pre>
{ 
 “post”: “Post ID”, 
 “author_name”: “Comment Author’s name”, 
 “author_email”: “Comment Author’s email”, 
 “content”: “Comment content”, 
 “parent”:”Comment parent ID” 
} 
 `
<blockquote>
Note: Ensure the parent is a comment id that belongs to the post informed in the field post. The comment parent post id must match the post id otherwise the following error will be shown:
</blockquote>
<pre><code>`Json
</code></pre>
{ 
 “code”: “rest_post_mismatch_parent_post_id”, 
 “message”: “Post ID and Parent post ID does not match”, 
 “data”: { 
 “status”: 400 
 } 
} 
 `

The simplest method to link WordPress with external APIs
JCI simplifies the task of retrieving data from a third-party REST API. The returned JSON-, XML, CSV, TXT-data can be neatly arranged and showcased on your WordPress site via a shortcode, a JCI Block or PHP. The plugin can generate a template for the data display.
20 seconds: Load API and display data

<h3>Main Plugin Features</h3>
<ul>
<li>Low code usage: Save time and avoid coding using an API</li>
<li>Insert an API-URL into Step 1: Data is loaded, and and displayed. Save it as API-Access-Set.</li>
<li>Use the API-Access-Set in Step 2 to create a Shortcode</li>
<li>Optional for maximum flexibility: Use the API-Access-Set n PHP code</li>
<li>Insert an API-URL into the JCI Block: Data is loaded, and a template can be generated to display the data.</li>
<li>Easy to start: Check Installation – Is your WordPress ready for JCI? Most probably!</li>
<li>Basic Settings: Check SSL, Cacher, Gutenberg and Authentication</li>
<li>ContactForm7 Integration: Populate CF7 forms with JSON data and forward CF7-submitted data to an API.</li>
<li>Use the JCI cacher to avoid many API requests</li>
<li>JCI-Block : Use the simple JCI Block interface to get data! Query the API and check the response. Then utilize the simple template generator inside the JCI Block to use the data!</li>
<li>Contact Form 7 Integration: Fill form and submit to API</li>
</ul>
<h3>Important Note Starting with Version 2.0.11</h3>
Starting with version 2.0.11, any HTML code present in the shortcode or block is filtered to prevent dangerous code (e.g. JavaScript) from being output. 
However, if you want to allow certain tags or attributes as a deliberate choice: 
In the plugin’s “Basic Settings” there is a field called “Allow additional HTML tags (advanced)”. 
There you can enter comma-separated tags that should not be filtered out. For example, “iframe,script” would preserve these two tags in the HTML output. 
“tr#onclick” would preserve the “onclick” attribute in ”, which would otherwise be removed.

<h4>JSON Content Importer PRO</h4>
Both the free and PRO JCI Plugins serve the same purpose: retrieving data, transforming it, and publishing the results. 
However, while the free Plugin can only handle basic challenges, the PRO JCI Plugin offers nearly full control over WordPress, the database, and applications. 
<a href="https://json-content-importer.com/compare/" rel="nofollow ugc">Compare: Free vs. JCI PRO Plugin</a>
PRO features: 
* application building by creating a searchform and connect it to a JSON-API in the background: pass GET-Variables to use a dynamic JSON-Feed-URL (“talk to API / webservice”) 
* much better and more flexible templateengine: twig 
* create and use Custom Post Types 
* store Templates independent of pages 
* more Shortcode-Parameters 
* executing Shortcodes inside a template 
* more features…

Get Use APIs – JSON Content Importer


All I wanted to do is display the latest version number of my own plugin on my site.  I could have spent hours coding it myself, instead I spent 5 minutes installing and working out this plugin.  Great work Bernhard


Easy Peasy


learning curve is very steep with the plugin but it simply works and i fell in love with it! i use it for everything: fetching flight prices, weather data, syncing wordpress blocks / content across different sites / domain through wp rest api to name a few!


such a clever plugin

Connects an API to WordPress: Get API-data (JSON, XML, CSV...), show it with a Shortcode, a JCI Block or PHP. Generate a template with the JCI Block
