Thread: Trigger on payment

We are setting up a store that sells both physical products we ship and downloaded products. I would like to be able to trigger an email at the point where the payment is authorized. We will be accepting credit cards, which uses a gateway and also purchase orders. Is there one place/event I can use which will tell me when the payment has been authorized? I couldn't find one in the list of events.

Thanks in advance

See this manual. If the transactionmode='AUTH', when someone purchased downloadable items, the links are not sent automatically to them upon placing the order. It's only sent once the order was captured manually via Orders -> View/Manage Orders, which is ideal.
