How to generate your own tokens.
Teslascope, along with all other 3rd-party Tesla services and applications are powered by the same APIs that Tesla's official mobile app uses. To access data about your vehicle(s) for the purpose of tracking trips or charging sessions, Teslascope uses tokens which can either be generated using your Tesla.com credentials, or by generating them yourself as explained below.
If you are on Mac OS or Linux, you can simply open up the application "Terminal" and type the following:
curl -X POST -H "Cache-Control: no-cache" -F "grant_type=password" -F "client_id=81527cff06843c8634fdc09e8ac0abefb46ac849f38fe1e431c2ef2106796384" -F "client_secret=c7257eb71a564034f9419ee651c7d0e5f7aa6bfbd18bafb5c5c033b093bb2fa3" -F "email=your email" -F "password=your password" "https://owner-api.teslamotors.com/oauth/token"
This can also be accomplished on Windows by installing "Bash for Windows" (Linux subsystem), or downloading and installing "Cygwin".
After pressing Enter, you should get a response that contains values for "access_token" and "refresh_token". You can now use these generated tokens to connect your Tesla.com account to Teslascope.
