What has to be considered is:
The Smart Lock 3.0 Pro has no included Bridge API, so every integration relying on the Bridge API will not directly work with the Smart Lock 3.0 Pro. So in these cases a Nuki Bridge is needed.
I am not sure where you created which API token though in your example.
(Preparing for the question why it is not included: Mapping the Bridge API functionality to the Smart Lock 3.0 Pro could lead to significant battery issues, as the Bridge normally caches everything possible to avoid constantly waking up the device.)
