Of course, such data also needs to be shown in mobile applications along with the possibility of updating them just after modification in the web-based part. What is more, some external data, for example, obtained from the sensors of mobile devices, may need to be entered into the system. These are only a few reasons why APIs are developed as a way of exchanging data between various parts of the system.
