# Managing Telegram Webhooks Using curl

Telegram bot webhooks allow you to receive updates and interact with users through a specified URL. This article covers how to set up, get, and delete webhooks for your Telegram bot using `curl`, along with explanations of all possible webhook-related operations.

## Prerequisites

- A Telegram bot token, which you can obtain from BotFather.
- A publicly accessible server or a tool like ngrok to expose your local server.

## 1. Setting a Webhook

To set a webhook for your Telegram bot, use the `setWebhook` method. This method tells Telegram where to send updates for your bot.

### Example Command

```bash
curl -F "url=https://yourdomain.com/uibot" https://api.telegram.org/bot<your-bot-token>/setWebhook
```

```bash
curl https://api.telegram.org/bot<your-bot-token>/setWebhook?url=https://yourdomain.com/uibot
```

Replace `<your-bot-token>` with your bot's token and `https://yourdomain.com/uibot` with your server's URL.

### Response

A successful response should look like this:

```json
{
  "ok": true,
  "result": true,
  "description": "Webhook was set"
}
```

### Detailed Command Example

For a bot token `123456789:ABCdefGHIjklMNO_pqrSTUvwxYZ` and a URL `https://58a1-223-176-63-126.ngrok-free.app/uibot`, the command would be:

```bash
curl -F "url=https://58a1-223-176-63-126.ngrok-free.app/uibot" https://api.telegram.org/bot123456789:ABCdefGHIjklMNO_pqrSTUvwxYZ/setWebhook
```

or Simply
```bash
curl https://api.telegram.org/bot123456789:ABCdefGHIjklMNO_pqrSTUvwxYZ/setWebhook
```
Do a get request on setWebhook it will automatically delete the webhook for security reasons(personally observed)

## 2. Getting Webhook Information

To get information about the current webhook, use the `getWebhookInfo` method. This method provides details about the webhook, such as the URL, pending updates, and the last error encountered.

### Example Command

```bash
curl https://api.telegram.org/bot<your-bot-token>/getWebhookInfo
```

### Response

A successful response might look like this:

```json
{
  "ok": true,
  "result": {
    "url": "https://yourdomain.com/uibot",
    "has_custom_certificate": false,
    "pending_update_count": 0,
    "last_error_date": 0,
    "last_error_message": "",
    "max_connections": 40,
    "allowed_updates": null
  }
}
```

## 3. Deleting a Webhook

To remove the webhook and switch to `getUpdates` mode, use the `deleteWebhook` method.

### Example Command

```bash
curl https://api.telegram.org/bot<your-bot-token>/deleteWebhook
```

### Response

A successful response should look like this:

```json
{
  "ok": true,
  "result": true,
  "description": "Webhook was deleted"
}
```

## 4. Setting a Webhook with Additional Parameters

Telegram allows you to set additional parameters when setting a webhook, such as the maximum number of connections or specific types of updates.

### Example Command

```bash
curl -F "url=https://yourdomain.com/uibot" \
     -F "max_connections=100" \
     -F "allowed_updates=message,edited_channel_post,callback_query" \
     https://api.telegram.org/bot<your-bot-token>/setWebhook
```

### Parameters

- `url`: Required. HTTPS URL to send updates to.
- `max_connections`: Optional. Maximum allowed number of simultaneous HTTPS connections to the webhook (1-100). Defaults to 40.
- `allowed_updates`: Optional. JSON-serialized list of update types you want your bot to receive.

### Example with Parameters

```bash
curl -F "url=https://58a1-223-176-63-126.ngrok-free.app/uibot" \
     -F "max_connections=100" \
     -F "allowed_updates=message,edited_channel_post,callback_query" \
     https://api.telegram.org/bot123456789:ABCdefGHIjklMNO_pqrSTUvwxYZ/setWebhook
```

## 5. Getting Updates in getUpdates Mode

If you do not set a webhook, you can still get updates using the `getUpdates` method.

### Example Command

```bash
curl https://api.telegram.org/bot<your-bot-token>/getUpdates
```

### Response

A successful response should look like this:

```json
{
  "ok": true,
  "result": [
    {
      "update_id": 123456789,
      "message": {
        "message_id": 1,
        "from": {
          "id": 123456789,
          "is_bot": false,
          "first_name": "John",
          "last_name": "Doe",
          "username": "johndoe",
          "language_code": "en"
        },
        "chat": {
          "id": 123456789,
          "first_name": "John",
          "last_name": "Doe",
          "username": "johndoe",
          "type": "private"
        },
        "date": 1610000000,
        "text": "Hello, world!"
      }
    }
  ]
}
```
