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 
 } 
} 
 `

REST API Comment

REST API Comment adds in the 'Comment creation' function to the Wordpress REST API.

Note: You probably do not need this plugin. The REST API already supports adding the query param <code>?_embed</code> to your URL and the response will then include all “embedded media”, including the featured image, and the data you get there is exactly what this plugin gives you. The only reasons to use this plugin at this point are if you prefer to have the featured image data in a top level field in the response rather than among other embedded media in the <code>_embedded</code> field, and if you always want the featured image data in the response rather than having to ask for it with <code>?_embed</code>. I still use this plugin because I do usually want both these things, but definitely give <code>?_embed</code> a try before using this plugin. 🙂
Version 2 of the WordPress REST API returns a <code>featured_media</code> field (formerly featured_image) on the post object by default, but this field is simply the image ID.
This plugin adds a <code>better_featured_image</code> field to the post object that contains the available image sizes and urls, allowing you to get this information without making a second request.
It takes this:
<pre><code>"featured_media": 13,
</code></pre>
And turns it into this:
<pre><code>"featured_media": 13,
"better_featured_image": {
 "id": 13,

The format of the response is nearly identical to what you would get sending a request to <code>/wp-json/wp/v2/media/13</code> or using <code>?_embed</code>. When no featured image has been set on the post the <code>better_featured_image</code> field will have a value of <code>null</code>.
I’ve done some basic performance tests that indicate the difference in response times with and without this plugin to be about 10-15ms for a collection of 10 posts and 0-5ms for a single post. For me this is much faster than making a second request to <code>/media/</code>, especially for multiple posts.
As of version 1.1.0, there is a filter <code>better_rest_api_featured_image</code> that allows you to add custom data to the better_featured_image field. The filter is directly on the return value of the function that returns the better_featured_image field. This can be used to do things like add custom image meta or an SVG version of the image to the response. Here’s an example of how you might use it:
<pre><code>add_filter( 'better_rest_api_featured_image', 'xxx_modify_rest_api_featured_image', 10, 2 );
/**
 * Modify the Better REST API Featured Image response.
 *
 * @param array $featured_image The array of image data.
 * @param int $image_id The image ID.
 *
 * @return array The modified image data.
 */
function xxx_modify_rest_api_featured_image( $featured_image, $image_id ) {

 // Add an extra_data_string field with a string value.
 $featured_image['extra_data_string'] = 'A custom value.';

 // Add an extra_data_array field with an array value.
 $featured_image['extra_data_array'] = array(
 'custom_key' => 'A custom value.',
 );

 return $featured_image;
}

Better REST API Featured Images

Does what id says, and it helps me a lot while building the theme in Angular2. Only one GET to have Post and Featured Image details!



Perfect! Must be in the API core

The Plugin works very well and saves time, thanks!



Works also with REST API V2

Thanks Martin.
This plugin does excectly what is says it would do.
And this should definitely be integrated in the main api code!!!



Great plugin, why is this not in the default API?

Awesome

Adds a top-level field with featured image data including available sizes and URLs to the post object returned by the REST API.
