How to access my thermostat data through other nest developer account?

I had instslled nest thermostat in my home (its really wonderful). I also created one nest devloper account om nest developers site. So i want to access (for ex. Deviceid or device name ) of my thermostat details through my nest developer account. How i can achive this?

I also tried following steps. But its unsuccessful.

1. Sign up nest developer account.
2. Created a cloud application.
3. I got the product id,product secret and authorization code.
4. I added my nest thermostat account to in family account.
5. I got the token and called device_id API using the token. But got the error as 401 unauthorized.

Please can some one help on this?

Once you have an access token, you should be able to retrieve all the device details using that access token. See API Read Examples for examples on how to use the access token.

Also, when using Family Accounts, keep in mind that only the structure owner can access the device information through the API.
