you have to use the HTTP-binding for this:

  1. using it as an item, which gets periodically updated (if it is just Information you Need)
    https://docs.openhab.org/addons/bindings/http1/readme.html#handling-json
  2. using it as an Action within a rule to trigger an Action or a realtime-information https://docs.openhab.org/addons/actions.html#http-actions

in both cases, you can transform the JSON into the string you’ll Need via simple JSONPATH Transformation:
