Import this package into your info-beamer account.

This package shows how you might build a package that contains both user controlled values as well as an automatically updated part that is updated only using the API.

The top-level node.json file specifies a playlist as an example of a user configurable option.

Inside the automated directory there's another node.json file. It shows two fields of type json that can be changed only using the API.

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'

Inside your node.lua code you can easily watch both the top-level config.json as well as the automated/config.json file using the util.json_watch helper function. See the node.lua code in the package for details.

Using the json data type for all configuration options allows you to place arbitrary values in the configuration itself and inside Lua you can directly access them in the util.json_watch callback. No extra parsing is required.
