Send a command with a curl

Looking at this post:

Controlling things with apple home

Hi! I was also searching for a function to control the Webthings Gateway with Apples HomeKit and found this post. As an alternative to control the Gateway with an Apple Device running iOS, you can use the API of Webthings and the Shortcut function of iOS. With Siri you can trigger a created shortcut. In the shortcut itself you are sending a PUT command to the API of the gateway to change the status of your smart Home device. Attached you can find my created example. It is working very good. …

It appears to be trivial to send a command to a thing from curl, but I’m obviously misunderstanding something.

I generated my Authorization, then have tried variations on this following curl command to turn on a TP-Link smart outlet:

curl -H "Authorization: Bearer [authorization token here]"   -H "Accept: application/json" https://[subdomain].mozilla-iot.org/things/tplink-[device_id]/properties/on -X PUT -d '{"on": true}'

From that command, I receive:
Invalid property name

If I try to connect with the local IP address of the gateway, I get:
Forbidden

Make sure you add -H "Content-Type: application/json" to your curl command.
