COINBASE_ACCOUNT_ID=YOUR-COINBASE-ACCOUNT-ID # this is optional, we'll use your primary_account if you don't specify this
and require the coinbase/wallet, e.g.:
require 'coinbase/wallet`
docproof_document = Docproof::Document.new('y0urd0cum3nt5ha256h45h')
docproof_document.register! && docproof_document.notarize!You can also configure the Coinbase API Key, Secret and Account ID like so:
require 'coinbase/wallet`

# Docproof::PaymentProcessor::Coinbase.configure do |config|
# config.api_key = 'YOUR-COINBASE-API-KEY'
# config.api_secret = 'YOUR-COINBASE-API-SECRET'
# config.api_secret = 'YOUR-COINBASE-ACCOUNT-ID'
# end
#
# or pass a hash as configuration (the hash key must be string)
Docproof::PaymentProcessor::Coinbase.configure(
'api_key' => 'YOUR-COINBASE-API-KEY'
