HTML bot response control
Use the HTML bot response control to display static HTML text in the Virtual Agent bot response.
Security considerations for HTML markup
For security reasons, an HTML sanitizer script runs automatically and checks all HTML markup used in the instance, including Virtual Agent conversations. The sanitizer script removes elements or attributes that might enable cross-site scripting attacks. You can edit the HTML sanitizer script to change the list of markup items to be preserved or removed. For details, see HTML sanitizer. For examples of adding markup items to the exclusion or inclusion lists, see Configure HTML sanitizer.
To disable the HTML sanitizer script only for Virtual Agent conversations, add the com.glide.cs.html.sanitizer.enabled system property and set the value to false. For details about creating a system property, see Add a system property.

Example HTML bot response output
The HTML bot response shows a static HTML as a chat response. This example includes an image, headings, and paragraph text. The web UI presents this content as HTML. The Slack, Microsoft Teams, and Workplace user interfaces display the same content as a PNG image. URL links within the HTML are extracted and displayed below the image. The URL can be either an absolute or a relative link. If you use a relative link, it must be relative to the ServiceNow instance.
