[Back to methods index](index.md)
Sends a service message to a secret chat.
### Parameters:
| Name | Type | Description | Required |
|----------|---------------|-------------|----------|
|peer|[Secret chat ID, Update, EncryptedMessage or InputEncryptedChat](../types/InputEncryptedChat.md) | Secret chat ID | Yes|
|message|[DecryptedMessage](../types/DecryptedMessage.md) | The service message | Yes|
### Return type: [messages\_SentEncryptedMessage](../types/messages_SentEncryptedMessage.md)

### 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_SentEncryptedMessage = $MadelineProto->messages->sendEncryptedService(['peer' => InputEncryptedChat, 'message' => DecryptedMessage, ]);
```
Or, if you're into Lua:
```lua
messages_SentEncryptedMessage = messages.sendEncryptedService({peer=InputEncryptedChat, message=DecryptedMessage, })
```
## 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\_SentEncryptedMessage](../types/messages_SentEncryptedMessage.md) will be returned instead.
