Hi,
We at OneStream Networks are developing an internal portal for employees that needs to interact with WHD to CREATE/DELETE/UPDATE companies in WHD. We didn't expect Solarwinds to not have API endpoint for company as it is an essential entity for us and many other WHD User's out there.
I would appreciate if you can take a look at this. I have raised a feature request on customer care and the issue is CUST-70755.
