How can I check programmatically if the user who is trying to buy the billing item in the application is its publisher?

Question

When I try to use a billing element in an application, its api shows that: "the publisher cannot buy this element"

I want to check my application, if the user himself, the Google Play Play user and the publisher of the application, are free for me, so how could I check programmatically if the user trying to buy an invoice object in the application is his publisher?
