Hi. I've successfully created a system to log in and query a client's PayPal account using the REST API. The type of query I'm doing is a transaction query. In the sample available, it showed payer information, but with the client's data, although I get the dates and amounts, no payer information is showing up. Some of the data is transfers so wouldn't have payer information, but some of it should at least have name and email and it's not coming through. What do I need to do to make sure the payer information is included?
