RESTful Switch - POST raw body data

I’m trying to use the RESTful switch to turn on and off my whole home audio channels. When POSTing the following via CURL, it works:

/usr/bin/curl -X POST http://nodejs.abl:8181/zones/11/pr -d '01'  
/usr/bin/curl -X POST http://nodejs.abl:8181/zones/11/pr -d '00'

When trying to use the following, GETs work, but when switching state with POST, my REST endpoint does not like the input its receiving from HA.

switch:
 - platform: rest
   resource: http://nodejs.abl:8181/zones/11/pr
   name: 'Channel 1'
   body_off: 00
   body_on: 01

Any idea if I can use the REST switch or do I have to use the command_line platform?

Bump. Any ideas?

You should give it a try with quotes for body_off and body_on. Could be that your values are evaluated by YAML before sending.
