+
+Types and helper functions that may come in handy when you implement a Discord Interactions webhook.
+
+# Installation
+
+Install from [packagist](https://packagist.org/packages/discord/interactions):
+
+```
+composer require discord/interactions
+```
+
+Validating request signatures requires the [`simplito/elliptic-php`](https://github.com/simplito/elliptic-php) package to be installed, which requires the `php-gmp` extension to be enabled:
+
+```
+composer require simplito/elliptic-php
+```
+
+# Usage
+
+Use `InteractionType` and `InteractionResponseType` to interpret and respond to webhooks.
+
+Use `InteractionResponseFlags` to make your response special.
+
+Use `verifyKey` to check a request signature. Note you must install the `simplito/elliptic-php` package first. For example:
+
+```php
+use Discord\Interaction;
+use Discord\InteractionResponseType;
+
+$CLIENT_PUBLIC_KEY = getenv('CLIENT_PUBLIC_KEY');
+
+$signature = $_SERVER['HTTP_X_SIGNATURE_ED25519'];
+$timestamp = $_SERVER['HTTP_X_SIGNATURE_TIMESTAMP'];
+$postData = file_get_contents('php://input');
+
+if (Interaction::verifyKey($postData, $signature, $timestamp, $CLIENT_PUBLIC_KEY)) {
+  echo json_encode(array(
+    'type' => InteractionResponseType::PONG
+  ));
+} else {
+  http_response_code(401);
+  echo "Not verified";
+}
+```
