account aka completed customer didn ejunkie enable few launch nearly number payment paypal processor proof purchase purchases ready receipt references serves thank-you-email transaction txn useful

Nearly ready to launch - did a few test purchases and noticed that ejunkie didn't provide a customer number number or receipt number on the thank you email - how do I enable this?

Thanks

sorry - never mind - found the receipt number

The "Transaction ID" (aka txn_id) would be the most useful, as that references a specific, completed payment in your PayPal (or other payment processor) account, and thus it also serves as a "proof of purchase".
