Du verlinkst auf den Zwift Mobile
API client, der in Python geschrieben ist.
Für JavaScript verlinkt das auf hier:

Da heißt es aber mit Stand 2018:
Zitat:
In July '08, this library was converted to use Zwift's new Developer
API, in accordance with Zwift's policies.
The Developer
API requires a special developer account, and won't work with regular rider accounts like before. Currently, Zwift is not able to offer developer accounts to hobby developers, but I'm hoping they'll be able to at some point. You can contact Zwift at
developers@zwift.com to register interest and ask for further information.
