### **Step 1: Prerequisites**
1. **Telegram Bot:**
   - Create a bot using [BotFather](https://core.telegram.org/bots#botfather) and get the bot token.
   - Add the bot to your Telegram group/channel and note the `chatId`.

2. **n8n Setup:**
   - Ensure the **Telegram** and **Error Trigger** nodes are installed.
---
### **Step 2: Configure the Workflow**
1. **Update Telegram Chat ID:**
   - Open the **Config** node.
   - Replace `telegramChatId` with your actual Telegram group/channel ID:
     ```json
     return [
       {
         \"telegramChatId\": 123456789, // Replace with your chat ID, format 123456789 or -123456789
       }
     ];
     ```

2. **Set Telegram Bot Credentials:**
   - Open the **Telegram** node.
   - Add your bot token in the **Credentials** section.

3. **Activate the Workflow:**
   - Toggle the **Active** switch to enable the workflow.
---
### **Step 3: Set Up Error Workflow**
1. Open the workflow where you want error notifications.
2. Go to **Settings** > **Error Workflow**.
3. Select **Telegram Error Notifier** from the dropdown.
4. Save the changes.
---
### **Step 4: Test the Workflow**
1. Trigger an error in the workflow.
2. Check your Telegram for the error notification, which includes:
   - Workflow name
   - Date and time
   - Execution URL
   - Last node executed
   - Error details
---
### **Example Notification**
```
Workflow: My Workflow 1
Data & Time: 2023-10-27T12:34:56Z
URL: https://n8n.example.com/execution/12345
Last Node: HTTP Request
Error Detail: Failed to connect to the server.
```
---
### **Troubleshooting**
- **No Notifications:**  
  Ensure the workflow is active, and the bot token/chat ID is correct.
- **Permission Issues:**  
  Ensure the bot can send messages in your Telegram group/channel.
