[Back to methods index](index.md)


Sends a message to a chat

### Parameters:

| Name     |    Type       | Description | Required |
|----------|---------------|-------------|----------|
|peer|[Username, chat ID, Update, Message or InputPeer](../types/InputPeer.md) | The destination where the message will be sent | Optional|
|reply\_to\_msg\_id|[int](../types/int.md) | The message ID to which this message will reply to | Optional|
|message|[string](../types/string.md) | The message | Yes|
|reply\_markup|[ReplyMarkup](../types/ReplyMarkup.md) | Reply markup for sending bot buttons | 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.
