Hi @JeremyBrainard
That's the endpoint "claim network devices" where you set networkID in the URL and serial Number in the request body
It will add the listed devices to the network

The other endpoint to claim order/devices into Organization dashboard is "Claim into Organization", which indeed claim the devices the first time into your dashboard
