Each HTML API call needs to be accompanied by an access token, with the exception of one call that retrieves an access token for the immediate session.
POSTÂ /v2/oath2/token
grant_type=password&username={username}&password={password}
The return value of this call is the access_token for this session for use in subsequent HTML API calls, and should be passed as a query parameter named "access_token."
The default system user name is "admin." Factory default password is the empty string, and can be modified from the device's Advanced menus.
