Using APIs which require an API key or authentication in JSON

At this time, authentication isn't supported by the JSON plugin. If the API you're trying to use requires authentication, you will be unable to pull content from it. If it requires an API key, you may be able to access the API if it allows passing the API key as a URL parameter but if it requires the key be passed in the body of the request or as a separate header then it won't work.

Though you can't access these APIs directly, the JSON plugin does let you import a local JSON file so you could use another API client to make your request, save the JSON file locally, and then reference it as a workaround.
