In this video, we walk through how to create a custom HTML widget inside a digital assistant to power advanced calls to action.
Using a banking example, we build a mortgage rate calculator that pulls live data from an API, passes parameters to the assistant, and renders an interactive HTML card. You’ll see how integrations are configured, how API responses are tested, and how parameters like loan term and down payment are mapped into the widget.
We also cover the template wizard, handlebars-based HTML rendering, and styling, showing how these widgets can guide visitors to take the next step directly within the assistant experience.
