Overview

Text messages are the simplest form of communication on Viber, supporting up to 1,000 characters (including spaces, emojis, and markdown symbols) with optional text formatting. Messages use UTF-8 encoding and support bold, italics, monospace, and strike through formatting using markdown syntax. Emojis can be added using emoji codes, and line breaks are supported. Text messages are available for both transactional and promotional categories.

Text formatting

Format	Markdown	Text to be sent	Message appearance
Bold	One asterisk at each end of the text: *	This text will be bold	This text will be bold
Italics	One underscore at each end of the text: _	_This text will be in italics_	This text will be in italics
Monospace	Three backticks at each end of the text: ```	```This text will be in monospace```	`This text will be in monospace`
Strikethrough	One tilde at each end of the text: ~	~This text will have a strikethrough~	~~This text will have a strikethrough~~
