https://developers.coinbase.com/docs/merchants/callbacks
id Order number used to uniquely identify an order on Coinbase
completed_at ISO 8601 timestamp when the order completed
status [completed, mispaid, expired]
event [completed, mispayment]. If mispayment => check key mispayment_id. Distinction from status ...
total_btc Total amount of the order in ‘satoshi’ (1 BTC = 100,000,000 Satoshi). Note the use of the word ‘cents’ in the callback really means satoshi in this context. The btc amount will be calculated at the current exchange rate at the time the order is placed (current to within 15 minutes).
total_native Units of local currency. 1 unit = 100 cents. Equal to the price from creating the button.
total_payout Units of local currency deposited using instant payout.
custom Custom parameter from data-custom attribute of button. Usually an Order, User, or Product ID
receive_address Bitcoin address associated with this order. This is where the payment was sent.
button Button details. ID matches the data-code parameter in your embedded HTML code.
transaction Hash and number of confirmations of underlying transaction.
Number of confirmations typically zero at the time of the first callback.
customer Customer information from order form. Can include email xor shipping address.
refund_address Experimental parameter that is subject to change.
