How to get opening and closing balance with List transactions API request

[Giancarlo39]

I'm downloading our transactions with the "List transactions" API in our with C# backoffice.
It allows us to download a maximum of one months transactions per request.
And a maximum of 3 years of history.

Now the question is, how do I get my opening and closing balance for the selected period?
I've tried the "List all balances" API, but that is only returning the balance of the requested date.

To answer my own (dumb) question, is that you can load the opening balance on the start date and do another request with the end date of the period.
