PayPal REST API: Search by BUYER Transaction ID

I asked that already in PayPal community, but basically almost all questions there get no answers.

How can I use the PayPal REST API to search by BUYER Transaction ID? The only way I know is via the PayPal website, but I need a REST API solution. A search via

https://api-m.paypal.com/v1/reporting/transactions?fields=all&transaction_id=[ID]&start_date=[DATE]&end_date=[DATE]

is successfull with the SELLER transaction id, but fails with the BUYER transation id.

There is also a SO thread from 2011, which basically has the same question, but was not answered either.
