It’s been a long while since we have played around with Widgetbox, but we recently ran into a site where Widgetbox was one of two whitelisted widget platforms so we re-visited their offerings.
This was perfect for what we wanted to do. We grabbed the embed code of the intended widget and pasted into the Widgetbox creation tool. This is where the Widgetbox hosted solution shines a little and was a nice surprise. They have created a method for you to replace sections of the code and inject param values based on user input at time of widget configuration. What this means is that, not only did we get to wrap the widget for our own use, but it also enabled others to grab either a copy of our widget or input their own id and get their own user specific widget.
Another thing that we noticed was that when you embed a widget, Widgetbox auto creates a widget panel. What this does is allow users to add new widgets to the destination site through the Widgetbox panel management system rather than embedding code again on the destination.
Overall, Widgetbox has a nice implementation that is easy to use. They are definitely one of the leaders in this space and we will need to check in on them more often.
