How can I export device details archive (including configurations, etc) for all devices on my map?

Hello @Sklink,
unless you want to access the database directly and get the data, you might want to try the following API calls which get data per device:

• Get Device Configration API.md
• Get Device Attributes API.md
• Get Device Data API.md

​​​​​I do not know of any exporting function otherwise. You can export data from inventory but this probably does not yield the data you want.
