This [data stream](../../datastreams/data-streams-introduction) handles Fitbit sensor data downloaded using the [Fitbit Web API](https://dev.fitbit.com/build/reference/web-api/), **parsed**, and stored in a MySQL database. Please note that RAPIDS cannot query the API directly; you need to use other available tools or implement your own. Once you have your parsed sensor data in a MySQL database, RAPIDS can process it.
Most people will only need `fitbitjson_*` because they downloaded and stored their data directly from Fitbit's API. However, if, for some reason, you don't have access to that JSON data and instead only have the parsed data (columns and rows), you can use this data stream.
