Message Formatting

If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.

BB codes allow you to format the text of messages: highlight fragments, add links, line breaks, and special inserts.

Most often, formatting is conveyed in the MESSAGE field of the im.message.add method.

What You Can Do

highlight text: [B], [I], [U], [S]
add a link: [URL=...]...[/URL]
create a line break: [BR] or \n
insert a command link: [SEND=...]...[/SEND], [PUT=...]...[/PUT]

Example of Sending a Formatted Message
