There is a few people working on it as there is apps that do it already for other brands on GitHub (search for “Unbox”). They are going to add their findings to that app very soon as it’s in testing. This writes the track to a text file or browser source so if your software can read from a text file, it will work.
It is unofficial but It’s in testing now. Hopefully we will have this one app to use with all DJ software.
Here is a sample:
EDIT: Here is Unbox GitHub - erikrichardlarson/unbox: Log and display your rekordbox / Serato / Traktor / VirtualDJ / DJUCED / Mixxx tracks as they're played
Someone is asking for something similar in the feedback/issues section Call external API when Track changes · Issue #13 · erikrichardlarson/unbox · GitHub
Maybe help with the project or customise that code? Hope it works.
