Looking at
https://en.bitcoin.it/wiki/MyBitcoin_SCI - Table of Keys & Values.
It would be good idea add actual keys as shown below.
amount
currency
payee_bcaddr
note
baggage
payee_name
success_url
cancel_url
and so on....
Anyone know 'SCI Payer' and 'SCI Transaction Number'? My automatic download store won't process orders without transaction/batch #.
