@mania To use the Lansweeper API (GraphQL) to access data your lansweeper installation would need to be a cloud installation (its possible to operate in hybrid mode, syncing your data to cloud and then access - while still staying with the on prem UI).
API Details - Welcome | Documentation – Lansweeper
If you are Lansweeper cloud and don't want to build for your self via the API's we also have an out of box Lansweeper Service Graph connector.
Lansweeper + ServiceNow for accurate and up-to-date CMDB
If it must be On prem there is an integration provided by syncfish
CI Syncronizer - Powered by Syncfish - Lansweeper
Alternatively you could build using JDBC - I've not tried this but there is a post on the community that might help
Integration with LanSweeper; synchronizing and rec... - ServiceNow Community
Hopefully this helps you (or others)
Cheers Iain
