+# WIRECARD
+
+### Introdução
+Esta API realiza compras através do modo ***BOLETO*** e modo ***CARTAO***, além de mostras todas as compras feitas.
+
+### Overview
+Things that the developers should know about
+Ao fazer uma compra via boleto, é retornado o código para pagamento. E ao fazer via cartão, é retornada uma mensagem de aprovado.
+
+Ambas url's de compras são iguais, porém é exemplificado duas possibilidades para representar o ***body*** a ser passado mediante a compra por boleto ou cartão.
+
+***Para ambas as compras, deve ser passado um cpf em formato string com 11 caracteres.***
+
+Para as compras com ***cartão*** os valores do  ***card_number*** e do ***card_cvv***, devem ser passados em formato string com 16 caracteres e 3 caracteres, respectivamente.
