If you are using php, You should be use <code>chr(10)</code> . Its working as like <code>'\n'</code> or <code>'&lt;br&gt;'</code>. Also you can use <code>&lt;center&gt;&lt;/center&gt;</code> . Its working for me.

Turns out <a href="https://stackoverflow.com/questions/5583507/line-break-in-facebook-status-update-via-graph-api">Line break in Facebook status update via Graph API</a> might give you what you are looking for:

Use \u000A

For me it solved my similar issue I had with Facebook SendApi for a Facebook Messenger Bot.

I had to use \n\n for the line break to work.

e.g.

shows following in facebook messenger

<pre><code>Sorry, We don't have any information ragarding this.

blocks|key|328803|text|我试着在用户触摸我的Messenger机器人开始之前，在欢迎文本中得到一个中断。我发现"\n“起了作用，但只适用于手机版的Messenger。它目前在网络上不起作用。假设这个问题会在某个时候得到解决，因为Facebook在本周(2016年9月12日)的博客文章中显示了断线现象(+https://messengerblog.com/bots/messenger-platform-1-2-link-ads-to-messenger-enhanced-mobile-websites-payments-and-more+)|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|328804|entityMap|0|LINK|mutability|MUTABLE|url|https://messengerblog.com/bots/messenger-platform-1-2-link-ads-to-messenger-enhanced-mobile-websites-payments-and-more^0|3W|3A|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I was trying to get a line break in the welcome text that shows up before users touch Get Started in my Messenger bot. I found that "\n" worked but ONLY in the mobile version of Messenger. It doesn't work on the web at the moment. Assuming that will get fixed at some point because Facebook shows line breaks in their blog post this week (9/12/2016) <a href="https://messengerblog.com/bots/messenger-platform-1-2-link-ads-to-messenger-enhanced-mobile-websites-payments-and-more" rel="nofollow">https://messengerblog.com/bots/messenger-platform-1-2-link-ads-to-messenger-enhanced-mobile-websites-payments-and-more</a>

blocks|key|326265|text|虽然它没有文档化，但我认为"\r\n“会起作用。Graph将json响应作为"\r\n“返回给具有行中断的消息或帖子。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|326266|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Though it is not documented, but I suppose "\r\n" would work.
Graph api returns the json response as "\r\n" for messages or posts having a line break.

blocks|key|328779|text|我不能百分之百确定你用什么语言来构建你的机器人，但是如果你在使用PHP，那么\n就需要用双引号来包装，例如|type|unstyled|depth|inlineStyleRanges|entityRanges|data|328780|++$message+=+"Message+\n+with+a+line+break";|code-block|syntax|javascript|328781|使用单引号(')是行不通的。|328782|不过，如果使用PHP，更好的解决方案是使用PHP_EOL常量|328783|不管你用什么语言来构建你的机器人，你都可能有类似的怪癖|328784|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I'm not 100% sure what language you're using to build your bot, but if you're using PHP then \n needs to be wrapped in double quote strings e.g

<pre><code> $message = "Message \n with a line break";
</code></pre>

using single quotes (') won't work.

Though a better solution if using PHP would be to use the PHP_EOL constant

Whatever language you're using to build your bot may have similar quirks

Use language specific line separators.

php PHP_EOL 

Python os.linesep

When we use special character in string then JSON conversion understand it as part of string.

Convert "\n" in your text to "\n" => it working...
With Php this is my code: (tested) 

<pre><code>$_text = str_replace(array("\r\n", "\r", "\n"), "\\n", $_text); 
</code></pre>

In Facebook Messenger chat,we can break a line by press "SHIFT+ENTER". 
So how to break line by Facebook Graph API(Messenger API). 
I've seen in a few answers that the Graph API accepts <code>&lt;center&gt;&lt;/center&gt;</code> instead of <code>&lt;br&gt;</code> and some other parts of their API seem to accept <code>\r\n</code>. 

Is there currently any way of sending a line break and if there is where it it documented?

在Facebook聊天中，我们可以通过按"SHIFT+ENTER“来打破一条线。那么，如何通过Facebook (Messenger API)打破底线。我在几个答案中看到图形API接受<center></center>而不是 ，他们的一些其他部分似乎接受\r\n。目前是否有任何方式发送中断线，如果有它的记录？
