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 
 } 
} 
 `

WordPress REST API endpoints are open and unsecured by default which can be used to access your site data. Secure WordPress APIs from unauthorized users with our <a href="https://plugins.miniorange.com/wordpress-rest-api-authentication" rel="nofollow ugc">JWT Authentication for WP REST APIs plugin</a>.
Our plugin offers below authentication methods to Protect WP REST API endpoints: 
– <a href="https://plugins.miniorange.com/wordpress-rest-api-jwt-authentication-method" rel="nofollow ugc">JWT Authentication</a> 
– <a href="https://plugins.miniorange.com/wordpress-rest-api-basic-authentication-method" rel="nofollow ugc">Basic Authentication</a> 
– <a href="https://plugins.miniorange.com/rest-api-key-authentication-method" rel="nofollow ugc">API Key Authentication</a> 
– <a href="https://plugins.miniorange.com/wordpress-rest-api-oauth-2-0-authentication-method" rel="nofollow ugc">OAuth 2.0 Authentication</a> 
– External Token based Authentication 2.0/OIDC/JWT/<a href="https://firebase.google.com/docs/auth/admin/create-custom-tokens" rel="nofollow ugc">Firebase</a> provider’s token authentication methods.
You can authenticate default WordPress endpoints and custom-developed REST endpoints and third-party plugin REST API endpoints like that of <a href="https://wordpress.org/plugins/woocommerce/" rel="ugc">Woocommerce</a>, <a href="https://www.learndash.com/" rel="nofollow ugc">Learndash</a>, <a href="https://wordpress.org/plugins/buddypress/" rel="ugc">Buddypress</a>, <a href="https://www.gravityforms.com/" rel="nofollow ugc">Gravity Forms</a>, <a href="https://wordpress.org/plugins/cart-rest-api-for-woocommerce/" rel="ugc">CoCart</a>, etc.

<h3>WP REST API Authentication Methods in our plugin</h3>
<ul>
<li><a href="https://plugins.miniorange.com/wordpress-rest-api-jwt-authentication-method#step_a1" rel="nofollow ugc">JWT Authentication</a> 
Provides an endpoint where you can pass the user credentials, and it will generate a JWT (JSON Web Token), which you can use to access the WordPress REST APIs accordingly. 
Additionally, to maintain a seamless user experience without frequent logins needed due to token expiry, you can use our Refresh and Revoke token mechanisms feature. 
When the access token expires, instead of forcing the user to log in again, the client can request a new access token using a valid refresh token.</li>
<li><a href="https://plugins.miniorange.com/rest-api-key-authentication-method#step_a" rel="nofollow ugc">API Key Authentication</a></li>
<li><a href="https://plugins.miniorange.com/wordpress-rest-api-basic-authentication-method" rel="nofollow ugc">Basic Authentication</a>: 
 – 1. Username: Password 
 – 2. Client-ID: Client-Secret</li>
<li><a href="https://plugins.miniorange.com/wordpress-rest-api-oauth-2-0-authentication-method#step_a" rel="nofollow ugc">OAuth 2.0 Authentication</a> 
 – 1. Password Grant 
 – 2. Client Credentials Grant</li>
<li><a href="https://plugins.miniorange.com/wordpress-rest-api-authentication-using-third-party-provider#step_a" rel="nofollow ugc">Third Party Provider Authentication</a></li>

<h3>Following are some of the integrations that are possible with WP REST API Authentication:</h3>
<ul>
<li>Learndash API Authentication</li>
<li>Custom Built REST API Endpoints Authentication</li>
<li>BuddyPress API Authentication</li>
<li>WooCommerce API Authentication</li>
<li>Gravity Form API Authentication</li>
<li>External/Third-party plugin API endpoints integration in WordPress</li>
</ul>
You can also disable the WP REST APIs with our plugin such that no one can make API calls to your WordPress REST API endpoints.Our plugin also provides Refresh and Revoke Token that can be used to improve the API security.
<h3>Benefits of Refresh Token</h3>
<ul>
<li>Enhances security by keeping access tokens short-lived.</li>
<li>Improves user experience with uninterrupted sessions.</li>
<li>Reduces login frequency.</li>
</ul>
<h3>Benefits of Revoke Token</h3>
<ul>
<li>Protects against token misuse if a device is lost or compromised.</li>
<li>Enables admin-triggered logouts or session control.</li>
<li>Useful for complying with stricter session policies.</li>
</ul>
With this plugin, the user is allowed to access your site’s resources only after successful WP REST API authentication. JWT Authentication for WP REST APIs plugin will make your WordPress endpoints secure from unauthorized access.
