Teams Graph API: Send multiline chat message (JSON content type)

Francois De La Roche 21

Hello there,

I'm having issue sending a multiline chat message in Microsoft Teams using the Graph API, I'm using this as reference: https://learn.microsoft.com/en-us/graph/api/chatmessage-post?view=graph-rest-1.0&tabs=http

Sending a message (via Postman) works, the example in page above gives this result:

But as soon as I try to introduce a line feed (or line return):

   {  
     "body": {  
       "content": "Hello World \nNew Line"  
     }  
   }

I'm always getting:

Things I have tried:

\r\n
\n\r
\n\n
\n+space+\n
3 spaces+\n
<br>\n
and probably others...

Would you be kind to let me know how to add a new line?

Thank you,
Francois

Hi @Francois De La Roche ,

Based on my test using "contentType": "html" will post the chat message in new line. Refer to the below sample request payload I used for my test.

POST /teams/{team-id}/channels/{channel-id}/messages  
{  
    "body": {  
        "contentType": "html",  
        "content": "Hello world<br/>New Line"  
    }  
}

Hope this helps.

@Srinivasa Rao Darna - I am also facing similar issue .. but in my scenario... I am posting the message in a existing Teams chat not in channel and content-type I have to use is "application/json" with POST method.

I have tried various option.. like <br />\n or \n or \r\n or \n .

None of them works... any suggestion. Thanks in advance
