'Is it somehow possible to get transaction details from any paypal user using my service?

Assume the following situation:
I have a 3rd party service offering some kind of analytics/report/whatever... on a paypal user's transaction history. Is it possible to fetch payments (only amount - in case that matters) of private paypal accounts (ofc assuming they somehow granted access by registering to my service), even though they didn't buy anything of me directly?

I hope the situation is somewhat clear, unfortunately I coulnd't find any matching questions on the web.

Thanks in advande!

It's easier to download activity and import a CSV than to query transactions via API, but there is a Transaction Search API that can be used.
