In Appian, to navigate from a record summary to an external URL, you can use a Button component configured with a 'Link' action. This approach allows you to define a URL that the button will navigate to when clicked. The Button component offers flexibility in terms of design and functionality, making it suitable for such navigation purposes within Appian interfaces. You can specify the URL directly in the Button's properties, allowing for dynamic link generation based on record data if needed.References
