Disabling Actions and Motion Capture via Web Server

This command appears to run properly, but doesn't actually disable the actions or motion capture for the specified camera as seen in settings for that camera:

do shell script "curl -k -d 'cameraNum=4&aTriggerHuman=0&aTriggerVehicle=0&aTriggerAnimal=0&aTriggerVideo=0&mcTriggerHuman=0&mcTriggerVehicle=0&mcTriggerAnimal=0&mcTriggerVideo=0' https://[username]:[password]@localhost:8001/settings-cameras"

--> "{\"camUpdate\":{\"num\":\"4\",\"name\":\"Bigfork North\"}}

I've tried separating the "a" and "mc" actions into different commands without success.

The command below does succeed at disabling a different camera:

do shell script "curl -k -d 'cameraNum=5&enabled=0' https://[username]:[password]@localhost:8001/settings-cameras"

--> "{\"camUpdate\":{\"num\":\"5\",\"name\":\"Bigfork Living Room\"}}"

What am I missing?

Thanks
