can you please give more details about tenants and the financial institutions. It is not very clear from the documentation.
For example, under the sandbox tenant which financial institutions are available?
How is it possible to find the tenant id of the financial institution (bank)?
Does every financial institution have its own tenant id?
Is it possible to get the list of all financial institutions in Dev/Test/Prod environments?
Is it possible to search for a customer along all existing tenants which belongs to the environment?
How is it possible to understand to which financial institution the customer belongs to?
