Created February 4, 2015 17:02
These are the result codes from Spanish payment gateway Redsys (formerly Sermepa) that I've managed to collect. The list is no doubt incomplete, and I'll be happy to update it if you have any more codes.
RESULT_CODES = (<<-EOT).split(/\r?\n/).reject {|s| s.match(/^( *#.*)?$/)}.map { |s| s.sub(/^ +/,'').split(/ +/,2) }.to_h
