Toggl API

I am trying to wrap my head around JSON to retrieve information from the Toggl API Toggl time tracking - Support and FAQ - API

What I can’t figure out being new to using JSON is how to convert the following string into a cfhttp request and I was hoping someone with some experience could give me an example.

 curl -u 1971800d4d82861d8f2c1651fea4d212:api_token -X GET
