Hi,

Im trying to get the parent tag of a device using the api in a powershell script. PRTG is at the newest update and you wont get a parent tag until you got on the Web UI on the device Settings and just click a few times around. Could it be that it is a bug or am i just doing something wrong?

This one works but only if you visited the Device on the WebUI Invoke-WebRequest -Uri "https:// **prtg** /api/getobjectproperty.htm?id= **deviceid** &name=parenttags&username=prtgadmin&passhash= **passwordhash**"

Thank you

Hi Marco,

Username and passhash are correct? What result do you get from Invoke-Webrequest?

Hi,

Yes im sure that those are correct since there is a reply getting to me.

Before visiting UI

Hi Marco,

Bug confirmed. I'll create an issue and link this thread to it. I'll let you know once it's fixed.
Would opening the device settings page via Invoke-Webrequest as an intermediate step work for you?
Because this will not be on high priority from what I can tell due to the low usage rate...
