I had a donation recently made to one of my games and would like to know the username of who made the donation, is it possible?

I checked the API and I couldn't find any API that could help me to map the email to the username.

If the buyer has a username it's shown in brackets after the email address. (Go to Payments - hover over the payment - click on details)

If the buyer doesn't have a username, only the email address is shown. (For example, if someone donated from the itch widget on my website.)

Oh, I see! I think in that case the donation was made without a username, then.

Thank you so much, I couldn't find this information anywhere.
