Device app for exchanging information

[paloma_c]

Hello,

I currently want to develop an application for the device that sends the personal information (biometric data such as heart rate, steps and so on) to an own web application (through APIs). I wanted to know if this could be done without sharing the information with the fitbit data services, and, in this case, which APIs should I use?

Huge thanks.

Yes, this can be done, but it's difficult. Use file transfer to get the data from watch to companion (phone), then fetch() from there to a server (which may be your web app).

But, do I need a phone in the middle to do this? I mean, the objective is to get the data from the watch directly to the application as none but except of the web application should get this data (is private).

Yes, you need a phone (or tablet) in the middle. The watch can only communicate with a phone. (This also applies to the Web API.)
