[Back to methods index](index.md)


Send a message

### Parameters:

| Name     |    Type       | Description | Required |
|----------|---------------|-------------|----------|
|peer|[Username, chat ID, Update, Message or InputPeer](../types/InputPeer.md) | The chat where to send this message | Optional|
|reply\_to\_msg\_id|[int](../types/int.md) | Reply to message by ID | Optional|
|message|[string](../types/string.md) | The message to send | Yes|
|reply\_markup|[ReplyMarkup](../types/ReplyMarkup.md) | Keyboards to send | Optional|


### Return type: [messages\_SentMessage](../types/messages_SentMessage.md)

### Can bots use this method: **YES**


### MadelineProto Example ([now async for huge speed and parallelism!](https://docs.madelineproto.xyz/docs/ASYNC.html)):


```php
if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$messages_SentMessage = $MadelineProto->messages->sendMessage(['peer' => InputPeer, 'reply_to_msg_id' => int, 'message' => 'string', 'reply_markup' => ReplyMarkup, ]);
```

Or, if you're into Lua:

```lua
messages_SentMessage = messages.sendMessage({peer=InputPeer, reply_to_msg_id=int, message='string', reply_markup=ReplyMarkup, })
```


## Usage of reply_markup

You can provide bot API reply_markup objects here.  



## Return value 

If the length of the provided message is bigger than 4096, the message will be split in chunks and the method will be called multiple times, with the same parameters (except for the message), and an array of [messages\_SentMessage](../types/messages_SentMessage.md) will be returned instead.
