Message formatting for bots
Important
This article is based on the v3 Bot Framework SDK. If you are looking for current documentation version 4.6 or later of the SDK, see the conversational bots section.
You can set the optional TextFormat
property to control how your message's text content is rendered.
Microsoft Teams supports the following formatting options:
TextFormat value | Description |
---|---|
plain | The text should be treated as raw text with no formatting applied at all. |
markdown | The text should be treated as Markdown formatting and rendered on the channel as appropriate; see Formatting text content for supported styles. |
xml | The text is simple XML markup; see Formatting text content for supported styles. |
Formatting text content
Teams supports a subset of Markdown and XML (HTML) formatting tags.
The following limitations apply:
- Text-only messages don't support table formatting.
- Rich cards support formatting in the text property only, not in the title or subtitle properties.
- Rich cards don't support Markdown or table formatting.
