What is Fitbit Intraday Heart Rate Data?

Fitbit Trackers which have Heart Rate sensors in them capture the Heart Rate continuously. However, Fitbit's App provides the Heart Rate information in 5-minute intervals.

This code allows you to download the detailed data from Fitbit's website and either see it on a chart, or download it in an Excel.

Why was this created?

I was quite emotionally charged up during a work seminar. Though I was sitting, I could feel my heart rate rising up. The Fitbit App was showing minimal heart rate increase, but I wanted to delve into more details. Since I could not find the detailed information easily available from the Fitbit App & Website, I used the Fitbit APIs to retrieve the data.

Tutorial on doing Fitbit OAuth2

I created a YouTube tutorial to showcase how you can configure your Fitbit Developer account to do OAuth2, and then get a "Client ID", which you can use in the code.
