<p>When a network error is encountered, API clients should be able to retry a request without a risk of their request being processed twice.<br />
WP API Idempotence adds support for clients to include an idempotency key that uniquely identifies that request. If the server detects<br />
that a request with the same key has already been processed or is currently being processed, the response for the initial request will<br />
be returned.</p>
<p>For Example:</p>
<pre><code>{
    "title": "My Important Post",
    "content": "This will only go out once!",
    "status": "draft",
    "idempotency_key": "1ced64e9-9537-4b7b-9919-444d9e15e201"
}
</code></pre>
<h4>Configuration</h4>
<ul>
<li>Idempotency key can either be passed in the request header or the request body.</li>
<li>The idempotency key name can be customized.</li>
<li>Change the HTTP methods the idempotency key is supported for. Defaults to <code>POST</code>, <code>PUT</code>, <code>PATCH</code>.</li>
</ul>
<p>A sample request interface is included to demonstrate the selected configuration.</p>
<h4>Developers</h4>
<p>The plugin includes two actions to modify the dependency injection container (DIC) and insert custom services.</p>
<p>The <code>wp_api_idempotence_initialize_container_builder</code> action allows you to modify the Dependency Injection builder itself and<br />
the <code>wp_api_idempotence_initialize_container</code> action allows you to override dependencies. For example:</p>
<pre><code>add_action( 'wp_api_idempotence_initialize_container', function( $container ) {
    $container->set( '_dataStore', DI\object( 'YourName\CustomDataStore' ) );
} );
</code></pre>
<p>Under the hood, the plugin is made up of a <code>DataStore</code>, <code>RequestHasher</code>, <code>ResponseSerializer</code> and <code>RequestPoller</code>.</p>
<p>The <code>DataStore</code> is primarily responsible for retrieving or storing an idempotent request. By default, requests<br />
are stored in a custom database table. This could be substituted for a custom driver by implementing the <code>DataStore</code><br />
interface. For example a Redis server.</p>
<p>The <code>RequestHasher</code> produces a unique hash for a <code>WP_REST_Request</code> object. This hash is based off of the contents of<br />
the request, not for the object via <code>spl_object_hash</code> or similar. This can also be substituted by implementing the<br />
    RequestHasher interface.</p>
<p>The <code>ResponseSerializer</code> converts a <code>WP_REST_Response</code> or <code>WP_Error</code> object back and forth from a string representation.<br />
The default JSON serializer supports filtering the serialization process using the <code>wp_api_idempotence_serialized_response_data</code><br />
and <code>wp_api_idempotence_attach_serialized_response_data</code> filters. See <code>src/ResponseSerializer/Filtered.php</code>.<br />
The entire serializer can be substituted by implementing the <code>ResponseSerializer</code> interface.</p>
<p>Finally, the <code>RequestPoller</code> class polls the data store for a response if it is determined that an idempotent request<br />
is currently being processed when another request with the same key arrives. By default, the data store is polled<br />
every seconds a maximum of 15 times to try and retrieve a response object. If no response is found, an error with code<br />
    rest_duplicate_idempotency_key will be returned. This can be adjusted by overwriting the <code>poll.sleepSeconds</code> and<br />
    poll.maxQueries in the DIC. The <code>RequestPoller</code> can also be entirely subsituted by implementing the <code>RequestPoller</code><br />
interface.</p>

WP REST API Idempotent Requests

Allow REST API clients to safely retry requests in case of network errors without risk of the request being processed twice.

<p><strong>WordPress REST API endpoints</strong> are <strong>open and unsecured by default</strong> through which anyone can access your site data. With our <strong><a href="https://plugins.miniorange.com/wordpress-rest-api-authentication" rel="nofollow ugc">REST API Authentication for WP plugin</a></strong>, secure your WordPress APIs from unauthorized users.</p>
<p><strong>Protect WP REST API endpoints</strong> from public access by:<br />

<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>
<p>This plugin will make sure that only after successful authentication, the user is allowed to access your site’s resources. REST API Authentication will make your <strong>WordPress endpoints secure from unauthorized access.</strong></p>
<p>Along with the default and standard WordPress REST API endpoints, with REST API Authentication for WP, you can authenticate 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.</p>
