+# Graph API Webhook TypeScript Sample
+
+This is a sample client for Facebook's [Webhooks](https://developers.facebook.com/docs/graph-api/webhooks/) product and Instagram's [Subscriptions API](https://www.instagram.com/developer/subscriptions/), powered by [Node.js](https://nodejs.org/en) and written in TypeScript.
+
+## Setup
+
+### Prerequisites
+Ensure you have Node.js installed.
+Create a `.env` file in the `typescript-server` directory with the following content:
+```env
+APP_SECRET=your_app_secret
+TOKEN=your_verify_token
+FROM_PHONE_NUMBER_ID=your_phone_number_id
+WHATSAPP_BEARER_TOKEN=your_app__bearer_token
+```
+
+### Instalation
+1. Navigate to the `typescript-server` directory:
+    ```bash
+    cd typescript-server
+    ```
+2. Install the dependencies:
+    ```node
+    npm install
+    ```
+
+### Running the Server
+1. Start the server in development mode:
+    ```node
+    npm run dev
+    ```
+2. Alternatively, build and start the server:
+    ```node
+    npm start
+    ```
+
+### Facebook Webhooks
+
+1. Refer to Facebook's [Webhooks sample app documentation](https://developers.facebook.com/docs/graph-api/webhooks/sample-apps) to see how to use this app.
+2. Set up your Facebook application's Graph API Webhooks subscription using `https://<your-domain>/facebook` as the callback URL.
+
+### Instagram Subscription API
+1. Register an [Instagram API client](https://instagram.com/developer/clients/manage/).
+
+2. Set up your client's [subscription](https://www.instagram.com/developer/subscriptions/) using `https://<your-domain>/instagram` as the callback URL.
+
+### Threads Webhooks
+1. Refer to [Threads' Webhooks Documentation](https://developers.facebook.com/docs/threads/webhooks) and set up Threads Webhooks product as a sub use case under the Threads API main use case.
+2. Set up your webhooks callback URL as `https://<your-domain>/threads`.
+
+## Endpoints
+`POST /facebook` - Handles Facebook webhook events.<br>
+`POST /instagram` - Handles Instagram webhook events.<br>
+`POST /threads` - Handles Threads webhook events.<br>
+`POST /whatsapp` - Handles WhatsApp webhook events.<br>
+`POST /message` - Sends a WhatsApp message.
