Windows DLL to RESTful Web API

Boleto Simples is a service for brazilian companies charge their clients using Boleto, a unique payment method in Brazil. The service has a public API ([login to view URL]) and clients written in Ruby ([login to view URL]) and PHP ([login to view URL]). We need a dll library to help developers integrate their desktop systems with Boleto Simples. This dll should have the same support as Ruby and PHP libraries already have. We have some examples of code: Ruby: [login to view URL] PHP: [login to view URL] Basically, the methods we need to be implemented are: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] The ideia is to allow any developer coding in Delphi, or VB ou .NET to include the DLL and use those methods.
