What do I put in for the ‘Publisher URL’ when creating a widget?
Feel free to use whatever naming conventions you would like for this field. Initially when widget builder was first conceptualized there was talk about making it a community where everyone could share widgets with each other. That is why these fields were created. There is still talk about that potentially down the road.
However right now, the fields like “Name, Description, Author, Publisher URL, Version” are all for you to use internally, and have no real impact on the actual functionality of the widget.
