Hi @sahithi,
Just as pointed out in the other thread at Preauth state to accepted state - #4 by TheYoctoJester, the device has to send the inventory. It’s not a management API call or such, but it is the device that needs to send out the data. If it doesn’t show up in a reasonable amount in time, then check the logs of the client device. Also as mentioned, you can also use the mender-update send-inventory command to trigger the update.
Greets,
Josef
