+WhatsApp Ping 🔔</h1>
+</div>
+
+Catching messages on Gmail from clients always has me running late, and checking it over and over can be a real drag. That's why I created `whatsapp ping`! It lets me ping myself on WhatsApp using a webhook.
+
+

+
+
+
+### Use Cases
+
+few use cases of this project generated by gpt.
+
+- 🔔 Instant Notifications: Get WhatsApp alerts for important client emails.
+- 📬 Stay Connected: Easily send quick messages to your team or clients.
+- 📅 Task Reminders: Schedule pings to remind yourself of upcoming tasks.
+- 🎉 Timely Notification: Wish your friend a happy birthday right on time.
+- 👨‍💻 Programmatic Use: Thanks to webhooks, integrate notifications into any app or service.
+
+### Usage
+
+clone or fork the repo and install all dependencies using your favorite package manager. In my case, i'm using `pnpm`.
+
+```bash
+pnpm i
+```
+
+**Prepare environment variables:**
+
+you need two env variables to make this work
+
+```env
+API_KEY=YOUR_API_KEY
+MONGO_URL=your_url
+
+# optional
+
+SELF_HOSTED=boolean -> set to true if running in self-hosted environment
+LOCAL=boolean -> for development purposes
+NEXT_MSG_DELAY=number > delays between next message 
+
+```
+
+We use `api-key` for authentication you can use any key you like to use but we recommend using strong key that is not vulnerable to `brute-force` attack.
+
+```bash
+openssl rand -base64 256
+```
+
+To run this bot in a serverless environment, we use MongoDB to manage the authentication state.
+
+You can Get the MongoDB URL for free from their [website](https://www.mongodb.com/).
+
+```js
+mongodb+srv://<user_name>:<password>@cluster0.usggwa4.mongodb.net/?retryWrites=true&w=majority
+```
+
+**start the server using the following command:**
+
+```bash
+pnpm dev # start development server
+OR
+pnpm start # start server in production
+```
+
+After starting the server, it will print QR code in the terminal scan it using your phone to connect whatsapp.
+
+### ⚓ Web Hook Usage
+
+Next use web hook as following to send a message,
+
+```c
+curl -X POST localhost:8080/ping \
+    -H "Authorization: Bearer $YOUR_API_KEY"
+    -d '{
+        "message": "hello world",
+        "numbers": ["123456789012"]
+    }'
+```
+
+using js,
+
+```js
+fetch("http://localhost:8080/ping", {
+  headers: {
+    Authorization: "Bearer YOUR_KEY",
+    "Content-Type": "application/json"
+  },
+  method: "POST",
+  body: JSON.stringify({
+    message: "hey",
+    image: "optional BASE64 image",
+    numbers: ["<country_code_without_plus><...number>"]
+  })
+})
+  .then((res) => res.text())
+  .then((res) => console.log(res));
+```
+
+### Caveats
+
+```diff
+- If you plan to deploy this project, it currently works only on VPS and not in a serverless environment. This means you will not be able to deploy it to the Vercel or other serverless providers.
++ We just added support for serverless deployment https://github.com/Zain-ul-din/whatsapp-ping/issues/2
+```
