The API documentation can be consulted by signing in to Awingu as an administrator.
Then navigate to Applications > System > API.
Alternatively, after authenticating, navigate to the "https://<awingu_ip_address>/api/v2/docs" page.
Example: https://demo.awingu.com/api/v2/docs .
The admin manual contains an additional chapter explaining how the API works, with an example on how to set up a session.
