We are using PowerBI as a reporting/display layer over our Workfront data. Using the WF API key, we make calls to Workfront every 30-minutes to pull data in a large JSON file and then transform that data in PowerBI to slice, filter, and visualize that data to suit our business needs. We heavily utilize the milestone pathway to standardize our projects so that we can compare their timelines side by side even with differing task names (think Gantt charts, etc.).
