It's a very good idea and cool that ServiceNow wants a package tracking option to improve their service. However, I don't know if FedEx is the best option. In addition, as far as I know, they have not yet adopted the tracking option. Another thing is the company https://www.postsendungsverfolgung.com/de/. With the help of their program, I track my parcels without any problems. By the way, this option has been around for a long time. So maybe you should pay attention to this company. This is a very cool idea.
