Marketing activities components reference

The form that's associated with a marketing activity app extension is generated based on a set of components that you choose when you create it. Components are configurable pieces of UI that you can use to build out the specific functionality that your app requires. Although a form is generated based on the components that you choose, you can't customize its styling, layout, or workflows directly.

To learn how to create a form for your app, refer to Getting started with marketing activities.
