Is this possible? I understand you can get it from the URL but I am building an app to utilize the API. I will have the user provide the username/password credentials. If that is sufficient to authenticate with the API can I get the idSite or "installation ID" from the API without having to have the user provide it? Otherwise I can try to login and get it from the URL for the user but I see this going badly and/or breaking when/if a change is made on the Victron side.
