To integrate BioStar 2 SW with 3rd party T&A system, there is a way to use BioStar 2 Local API. BioStar 2 Local API connects BioStar 2 Server and gets the log data with the proper parameter in the /api/events/search.
If you use the API named POST /api/events/search, you can retrieve the event logs through the API.
Also, when using the API, if you refer to the 'Model' in the API, you can find and check the information for each parameter.
Please refer the details to the video below about POST /api/events/search.
