Text Types

It is possible to add different types of lines to the chat. When no text type is defined, it is assumed that a plain type was submitted.

Best Practice: our embedded window relies on the LE Agent UI to display the above sent text in an HTML format with a "<div>" wrapper. Therefore, to make sure that the LiveEngage UI displays your text correctly, it is important to use the HTML format as seen in the example above. The provided html cannot include the following: Iframes, Scripts, DOM actions, Links with a target other than "_blank".

Changing the text type is handled as follows:

Name Description Notes
plain The default type when non used, the text will be displayed as provided  
html For passing HTML content from the agent to the chat session. The provided html cannot include the following: Iframes, Scripts, DOM actions, Links with targets (all targets will be rewriten to "_blank").
rich-content For passing Structured Content templates Refer to the Structured Content Templates document
