Hi there,
I’m trying to use the device inventory API on our self-hosted open source instance (`https://example-instance/api/management/v1/inventory/devices?Tag=00999`) to look for a device with a specific tag value, however for some reason it returns a blank array. There is a device in a group that contains this tag, and the tag is filterable as an “attribute”, as it’s displayed under attributes when I query the device ID, and is shown as such when I query `https://example-instance/api/management/v2/inventory/filters/attributes`.
Any idea where I could be going wrong here?

Hey,
You need to add scope to the query - try `https://example-instance/api/management/v1/inventory/devices?tags/Tag=00999`

That worked! Thanks for your help! 😄
