I need to clarify @rishat007 response a bit
Health API is available but is useless for new developers. It was for Tizen based watchs (Galaxy Watch3 and older) but only in developer mode and you needed a special key to even test on your device. You can’t get that key any longer.
Privileged partners is only available for US developers, the EU is in the works may already be available. That is for Galaxy Watch4 and newer devices.
You don’t need to be a privileged partner to get most of what you want as a normal developer. It is more for corporations who already have Health apps. Samsung and Google have paired to develop Wear OS Health Connect and Wear OS Health Services
There are several blog tutorials created in 2022 that should help you get started without needing Samsung Health API.
