Auth0 authentication with SharePoint REST api

Thanks Thomas, I'll definitely check out those Node tools. The users will need permissions. I know theres a way to get Office365 groups from Auth0 for use in custom applications but this is the first time ive used Auth0 so not sure of the process with setting everything up I do have all the users in Office365 groups with assigned permissions so they can access the specific sites, folders, files, etc. I do have a web app setup and registered with Azure, which I assigned specific permissions for the app, but I'm not sure if I need to do any other form of backend authentication with the app when I interact with the SharePoint API for uploading foles to SharePoint Sites, or if just the Auth0 authentication I have in place will be enough. I havent used the SharePoint API before and not too sure how it works. Thanks again
