Hi @Charan0105 ,

as far as I know, there is no single API to add devices to NetBrain. Devices are added through discovery. To get there is a little complex. You need to create a Discovery Task in NB, connect to NB, authenticate and select your domain, add devices to the task and run the task.

Create a Discovery Benchmark
Make sure to select API Triggered Discovery

These are the APIs to use, they all provide example code:
Login
Authentication and Authorization API

Select Domain
https://github.com/NetBrainAPI/NetBrain-REST-API-R11/blob/main/REST%20APIs%20Documentation/Authentication%20and%20Authorization/Specify%20A%20Working%20Domain%20API.md

Add Device to previously configured discovery benchmark

For cleanup, remove the list fo IPs from the discovery taskhttps://github.com/NetBrainAPI/NetBrain-REST-API-R11/blob/main/REST%20APIs%20Documentation/Discovery%20Task%20Management/Delete%20Seed%20IPs%20to%20Discovery%20Task%20API.md
