A tenant is your software, consuming the Finqware API. It usually has two components:
a client-side application (eg: a mobile and/or a web front-end)
a server. This is where you run the business logic, the user database etc.
It's important to make a clear distinction between the two. There are specific data items (i.e. tokens, secrets) that you can safely store in your client app, and others that we recommend to be used only in a server-to-Finqware communication.
A servicer may register multiple tenant apps for different business cases or just for technical reasons (eg: test & prod apps).
For a granular access control and reporting, each tenant is required to register the list of skills it connects to.
