The Widget SDK lets you override default message formatting using templates to display custom-formatted bot messages in the Widget SDK channel. For Web/Mobile SDK templates, see Web & Mobile SDK Message Formatting and Templates.

​
Template Types

Widget SDK templates support two header option types:
  • url — Opens an external site.
  • postback — Triggers an utterance in the assistant. The payload defines the utterance; nlmeta provides additional context to trigger the task.
