A Link Action is a workhorse. It points to any URL, including a website, blog, survey, app, or generally anything on the web.
After selecting the Link Action, paste the destination URL in the URL box. Cutting an pasting the URL is always best to make sure you get the entire URL. It must inlcude the "https://."
The "Fetch" button will retrieve and populate any available metadata (i.e., title, description, image) to the Action's call-to-action. You can edit it once retrieved.
**Make a Home Button: If you leave the URL field blank, then the Action will act as a home button. Add this to a subpage to easily return to the home screen. This action may be shared across many apps and will act as a home button for the current host app.
Reference the Action Formatting and Controls FAQ for a refresher on the controls that are common to Actions.
