Payment API for donation with Transparent Checkout

My site should receive donations. I integrated with the PagSeguro API, and the only modality available for donation is the "donation button". But it was not enough. I need something more like transparent checkout, that is, store donor data via API, but do not have automatic emails like transparent checkout (which come with texts like "thank you for your purchase"). Any suggestion of payment API or solution that supports donation via transparent checkout?
