Import this package into your info-beamer account.
Updating is easy:
curl -u:$API_KEY https://info-beamer.com/api/v1/setup/$SETUP_ID -d 'config={"automated":{"config_value1":{"foo":"bar"}}}&mode=update'
(Note: You shouldn't use raw curl for the API as the arguments to config should be urlencoded. Use a propery HTTP request library in your language of choice to do this correctly.)
By specifying the mode=update parameter, the above call only changes the
config_value1 value in the automated subdirectory. The user made settings
in the top-level node remain unchanged. If you have multiple json types in your
node.json, like in this example, you can of course also modify them all
at once with a single HTTP call:
curl ... 'config={"automated":{"config_value1":{"foo":"bar"},"config_value2": 1234}}&mode=update'
